How parent leads are calculated

Automated leads use birth surnames—not married surnames—as parental eligibility, role-specific biological age limits, bounded and approximate-date uncertainty, household chronology, specific time-aware localities, mapped distance, tenancy succession, migration destinations and sex-aware Scottish naming positions across generations. People already attached as the subject's parents stay in the identity summary and are excluded from this alternative-candidate list, regardless of relationship confidence. The main calibration uses clues available on disconnected profiles; existing parent and sibling links are retained as comparison context rather than treated as transferable evidence. Common ordered names and grandparent-to-child echoes receive a small non-zero weight, so a John or James match can support several independent criteria without producing a lead alone. Rare names, repeated bearers and bundles across otherwise distinct branches receive substantially more weight according to catalogue frequency. An exact migration place is weighted by its rarity and repetition across both branches; a shared destination country is worth only one point. Extra weight is added only when at least three independent clue types converge: naming, locality, specific migration, household chronology or collateral networks. Sparse profiles retain a clearly labelled chronology-only fallback instead of disappearing. Countries, states, counties and research clusters do not count as a shared locality, and fallback, broad representative or kin-inferred coordinates are excluded from distance scoring. Shared descendant profiles are removed before branch-name comparison. A candidate already recorded as a parent-in-law is excluded. A confident or independently supported parent is treated as settled; uncertain and unassessed attachments remain open to alternative comparison. A different linked parent, an uncle/aunt or grandparent path, and a matching existing child profile prevent an alternative from being classified as a strong direct-parent lead until the underlying tree conflict or duplicate is resolved. Familiar forms such as Bessie are normalised. Surname remains an eligibility filter worth zero points.

Naming customs, shared farms and occupations are circumstantial. Children, spouses and collateral relatives may be missing, and tree-derived family networks are not independent evidence. Scores rank research leads; they do not prove parentage.

Current conclusion

Glasgow-3556 · updated 2026-08-09

Thomas is a genuine adult Donegal actor documented at Lifford in 1689 and in the Raphoe/Ballindrait-Shannon property network from 1692 to 1695. These records do not prove an Irish birth, exact age, spouse, children or relationship to Archibald of Ramelton, Nathaniel of Keady/Fintona, or the later Killybegs James.

The 1693 Ballindrait material is also published with the surname Glascow. Together with Archibald's Glasgow/Glascoe forms, the chronology, uncommon surname and Donegal geography make a close Archibald-Thomas relationship a reasonable working hypothesis. They still do not establish father, uncle, brother or another degree.

Glasgow-3556 · updated 2026-08-09

  1. Add the 1689 Lifford attainder-list occurrence and the 1692–1695

Ballindrait/Shannon deed sequence.

  1. Use born before 1689, place unknown, rather than a certain 1670 County

Donegal birth.

  1. Describe him as a documented Esq. and legal/property actor, not as landed

elite unless estate ownership is separately proved.

  1. Do not attach him as son of Archibald-1101 or father of Nathaniel-1136.
  2. Keep Thomas Glasgow-1103, the Scottish child baptised in 1612, separate from

this Lifford man unless a cross-channel identity record is found.

  1. Treat the Scottish Thomas baptised in 1612 as a competing family-structure

lead: the Donegal Thomas could belong to his descendants rather than being Archibald's son. Do not identify the men on chronology alone.

  1. Search probate and Betham material under Glasgow, Glascow, Glascoe,

Glasco, Glassgow and Glasgua.

Suggested edit summary: Add the 1689 Lifford occurrence and qualify birth, status and proposed kinship.

Record-bearing passages

  • Biography The date and place of birth of Thomas Glasgow are unknown. Because he was recorded as an adult and styled an esquire in 1689, he was probably born before 1671; his precise age is unknown. No inspected record identifies his parents, wife or children.
  • This establishes that Thomas was associated with Lifford, County Donegal, and was styled an esquire by 1689. It does not establish his birthplace, precise age, land ownership or family relationships. Lifford is retained in the structured birth-place field as an uncertain locality lead, not as a proved birthplace.
  • On 23 December 1692, Thomas entered into a counterpart deed of partition with Colonel Abraham Creighton of Crom, County Fermanagh, and Abraham’s son James Creighton. The transaction concerned lands associated with the Leitrim estate in County Donegal. Public Record Office of Northern Ireland, D1939/18/8/1, counterpart deed of partition, 23 December 1692.
  • On 25–26 May 1693, Thomas was described as “of Ballindroight” in a lease and release made with Colonel Abraham Creighton. The transaction concerned lands including Drumloane, Glencosh and Shannon in the Barony of Raphoe. Public Record Office of Northern Ireland, D1939/18/1/3, lease and release between Thomas Glasgow of Ballindroight and Colonel Abraham Creighton, 25–26 May 1693.
  • On 26 May 1693, Thomas executed a bond for performance and a deed of defeasance in the sum of £4,000 in favour of Abraham Creighton. These instruments secured the performance of covenants associated with the property transactions. Public Record Office of Northern Ireland, D1939/18/3/25, bond and deed of defeasance, 26 May 1693.
  • A counterpart release of the same date, involving a consideration of £400, concerned lands including Teroneal, Drumlane, Glancosh and Shannon in the Barony of Raphoe. Public Record Office of Northern Ireland, D1939/18/7/1, counterpart release, 26 May 1693.
  • On 26 May 1694, Thomas was described as “of Shannon” when he issued a copy bond for performance of the covenants contained in a release to Abraham Creighton. Public Record Office of Northern Ireland, D1939/18/11/16, copy bond for performance of covenant, 26 May 1694.
  • On 25 November 1695, Thomas appeared in a letter and memorandum concerning a joint bond of £6,000 with Hugh Hamill, Abraham Creighton, John Hamilton and John Johnston, all described as esquires. Public Record Office of Northern Ireland, D1939/18/3/25, letter and memorandum, 25 November 1695.
  • Thomas was therefore alive on 25 November 1695. His later life, death date and place of death have not been identified. Identity and Status The references to Thomas Glasgow of Lifford, Ballindroight and Shannon almost certainly concern the same man.
  • The surname was uncommon, the locations were within the same Donegal and Raphoe property network, and the records form a continuous sequence of transactions involving Abraham and James Creighton between 1692 and 1695.
  • No inspected record explicitly states that the Thomas of Lifford was the same person as the Thomas of Ballindroight or Shannon. The identification is nevertheless strongly supported by the chronology, geography and repeated association with the Creightons.
  • Thomas was styled esquire and participated in substantial legal and financial transactions. The bonds, considerations and lands involved show that he was a significant actor in the Donegal property network.
  • He should therefore be described as an esquire and legal or property actor. The records do not by themselves prove that he beneficially owned every estate or parcel named. Family and Relationship Research The available records name Thomas Glasgow, Abraham Creighton, James Creighton and several other parties to the transactions.
  • No inspected record proves that Thomas was a son, brother, nephew or other relative of Archibald Glasgow M.A. (1614–bef.1677).
  • The chronology and geography allow Thomas to have been a son or younger relative of the Archibald Glasgow who served as a clergyman in County Donegal and whose will was proved in 1677. That remains a research hypothesis only.
  • No inspected record proves that Thomas was the father of Nathaniel Glasgow M.A. (died 1743).
  • No spouse or child should be attached to Thomas from chronology, geography, naming patterns or unsourced family trees alone.

Biography
The date and place of birth of Thomas Glasgow are unknown. Because he was recorded as an adult and styled an esquire in 1689, he was probably born before 1671; his precise age is unknown. No inspected record identifies his parents, wife or children.

In 1689, a printed list associated with the Irish attainder legislation named “Thomas Glasgow of Lifford, in the County of Donnegal, Esq.” among Protestants regarded as absent from Ireland or adherents of William of Orange. The State of the Protestants of Ireland under the Late King James's Government, list of persons named in the attainder legislation, p. 275. https://quod.lib.umich.edu/e/eebo/a47446.0001.001/1%3A6 

This establishes that Thomas was associated with Lifford, County Donegal, and was styled an esquire by 1689. It does not establish his birthplace, precise age, land ownership or family relationships. Lifford is retained in the structured birth-place field as an uncertain locality lead, not as a proved birthplace.

On 23 December 1692, Thomas entered into a counterpart deed of partition with Colonel Abraham Creighton of Crom, County Fermanagh, and Abraham’s son James Creighton. The transaction concerned lands associated with the Leitrim estate in County Donegal. Public Record Office of Northern Ireland, D1939/18/8/1, counterpart deed of partition, 23 December 1692. 

On 25–26 May 1693, Thomas was described as “of Ballindroight” in a lease and release made with Colonel Abraham Creighton. The transaction concerned lands including Drumloane, Glencosh and Shannon in the Barony of Raphoe. Public Record Office of Northern Ireland, D1939/18/1/3, lease and release between Thomas Glasgow of Ballindroight and Colonel Abraham Creighton, 25–26 May 1693. 

On 26 May 1693, Thomas executed a bond for performance and a deed of defeasance in the sum of £4,000 in favour of Abraham Creighton. These instruments secured the performance of covenants associated with the property transactions. Public Record Office of Northern Ireland, D1939/18/3/25, bond and deed of defeasance, 26 May 1693. 

A counterpart release of the same date, involving a consideration of £400, concerned lands including Teroneal, Drumlane, Glancosh and Shannon in the Barony of Raphoe. Public Record Office of Northern Ireland, D1939/18/7/1, counterpart release, 26 May 1693. 

On 26 May 1694, Thomas was described as “of Shannon” when he issued a copy bond for performance of the covenants contained in a release to Abraham Creighton. Public Record Office of Northern Ireland, D1939/18/11/16, copy bond for performance of covenant, 26 May 1694. 

On 25 November 1695, Thomas appeared in a letter and memorandum concerning a joint bond of £6,000 with Hugh Hamill, Abraham Creighton, John Hamilton and John Johnston, all described as esquires. Public Record Office of Northern Ireland, D1939/18/3/25, letter and memorandum, 25 November 1695. 

Thomas was therefore alive on 25 November 1695. His later life, death date and place of death have not been identified.
Identity and Status
The references to Thomas Glasgow of Lifford, Ballindroight and Shannon almost certainly concern the same man.

The surname was uncommon, the locations were within the same Donegal and Raphoe property network, and the records form a continuous sequence of transactions involving Abraham and James Creighton between 1692 and 1695.

No inspected record explicitly states that the Thomas of Lifford was the same person as the Thomas of Ballindroight or Shannon. The identification is nevertheless strongly supported by the chronology, geography and repeated association with the Creightons.

Thomas was styled esquire and participated in substantial legal and financial transactions. The bonds, considerations and lands involved show that he was a significant actor in the Donegal property network.

The surviving catalogue descriptions do not establish his precise role in every transaction. Depending upon the instrument, he may have acted as:

* owner;
* purchaser;
* vendor;
* mortgagee;
* trustee;
* tenant;
* surety; or
* another party with a legal interest.

He should therefore be described as an esquire and legal or property actor. The records do not by themselves prove that he beneficially owned every estate or parcel named.
Family and Relationship Research
The available records name Thomas Glasgow, Abraham Creighton, James Creighton and several other parties to the transactions.

They do not identify Thomas’s:

* father or mother;
* wife;
* sons or daughters;
* brothers or sisters;
* heirs;
* executors; or
* other stated relatives.

No family relationship between Thomas and the Creightons is given. Their repeated appearance together establishes a continuing legal and financial association, not kinship.

No inspected record proves that Thomas was a son, brother, nephew or other relative of Archibald Glasgow M.A. (1614–bef.1677).

The chronology and geography allow Thomas to have been a son or younger relative of the Archibald Glasgow who served as a clergyman in County Donegal and whose will was proved in 1677. That remains a research hypothesis only.

No inspected record proves that Thomas was the father of Nathaniel Glasgow M.A. (died 1743).

The proposed line:

Archibald Glasgow
|
?
|
Thomas Glasgow of Lifford, Ballindroight and Shannon
|
?
|
Nathaniel Glasgow

remains unsupported by direct kinship evidence. Each question mark represents a missing documentary link.

A James Glasgow appearing in Killybegs account material in 1728 may belong to an adjacent generation of the Donegal family. The entry does not identify James as Thomas’s son or other relative.

No spouse or child should be attached to Thomas from chronology, geography, naming patterns or unsourced family trees alone.
Distinction from Other Men Named Thomas Glasgow
Thomas should not be identified with Thomas Glasgow, the child baptised in Scotland in 1612, without evidence connecting that person to Lifford or County Donegal.

A man baptised in 1612 would have been approximately 77 years old in 1689 and over 80 during the property transactions of 1692–1695. That identity is chronologically possible but unlikely and is unsupported by any inspected cross-channel record.

The two profiles should remain separate unless a deed, will, migration record or other contemporary source establishes that they were the same person.
Death
Thomas’s date and place of death are unknown.

He was alive on 25 November 1695, when he was named in the memorandum concerning the £6,000 joint bond.

No will, administration, burial entry or record naming his heirs has yet been identified.

His profile should therefore use:

* birth probably before 1671, based on adult status by 1689, with birthplace unknown; and
* death after 25 November 1695, place unknown.

The year 1670 and County Donegal should not be presented as a certain birth date and place without an independent source.
Locations Associated
* Lifford, County Donegal — Thomas’s stated residence or association in the 1689 attainder list.
* Ballindroight, Barony of Raphoe, County Donegal — his stated residence in the May 1693 lease and release.
* Shannon, Barony of Raphoe, County Donegal — his stated residence in the May 1694 bond.
* Drumloane, Glencosh, Glancosh, Teroneal and Drumlane — lands named in the Creighton transactions.
* Crom, County Fermanagh — residence of Colonel Abraham Creighton, Thomas’s principal associate in the surviving deeds.

The place-name Ballindroight may represent Ballindrait or another historical spelling. The original deeds and contemporary maps should be consulted before standardising the location.
Research Notes
The PRONI catalogue summaries may omit details contained in the original documents. Full copies could include:

* witnesses;
* seals and signatures;
* endorsements;
* former owners;
* inheritance recitals;
* adjoining tenants;
* trusts;
* marriage settlements;
* occupations;
* residences; or
* statements of family relationships.

The complete documents should therefore be inspected before concluding that they contain no genealogical evidence.

Particular attention should be given to phrases such as:

* “son and heir”;
* “natural and lawful son”;
* “brother”;
* “kinsman”;
* “heirs of the body”;
* “in consideration of marriage”;
* “for the advancement of”; and
* “remainder to”.

Further research should concentrate on:

* complete copies of PRONI D1939/18/8/1, D1939/18/1/3, D1939/18/3/25, D1939/18/7/1 and D1939/18/11/16;
* indexes to Irish prerogative and Raphoe diocesan wills and administrations;
* Betham will and administration abstracts;
* Donegal deeds involving the Creighton estate;
* Registry of Deeds memorials created after 1708;
* Raphoe parish and diocesan records;
* Lifford corporation and court records;
* Donegal Grand Jury records;
* records concerning the 1728 Killybegs James Glasgow; and
* later conveyances showing who inherited or occupied the lands after Thomas disappeared from the record.
Research Conclusion
Thomas Glasgow was a genuine adult Donegal figure documented at Lifford in 1689 and in the Ballindroight and Shannon property network from 1692 to 1695.

He was styled an esquire and participated in substantial legal and financial transactions with Abraham and James Creighton. The documents do not establish that he owned every property named.

His birth date and place are unknown. His adult status in 1689 supports a probable birth before 1671, and the records show that he was alive after 25 November 1695.

No inspected record identifies his wife, children, parents, heirs or siblings. No relationship to Archibald Glasgow of Ramelton, Nathaniel Glasgow of Golan or Fintona, the later Killybegs James Glasgow, or the Scottish Thomas baptised in 1612 has been proved.
