No named children are recoverable, so child-naming analysis cannot be run.

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.

How duplicate leads are calculated

Dates are eligibility gates, not merely deductions: chronologically impossible people are excluded. Dates, places, spouses, parent certainty and children's profiles and names are then compared. A high score is a prompt to inspect records, not a merge recommendation.

Current conclusion

Glasgow-549 · updated 2026-07-21

John is known only from William Melanchthon Glasgow's late family history, which names him first among three sons of Hugh Glasgow and Margaret McCullough. The account supplies no birth date, residence, wife, child or death. The current about-1735 County Londonderry birth and about-1785 death are unsupported.

No found record directly connects this John to Adam Glasgow or John Glasgow of Inishrush. He is chronologically capable of fathering both men, as is his traditional brother Robert. The late family history places their brother Hugh's family farm near Portglenone by 1780, independently consistent with the local 1740, 1772 and Inishrush evidence.

No evidence distinguishes this John from Robert-550 as the direct father. John born 1767 used John in the third-son position, which already repeats his own name; his first son Adam therefore points more naturally to an older Adam as paternal grandfather than to this profile. The existence of a second local Hugh householder in 1740 supplies a possible collateral root for that older Adam/Maria model.

William Melanchthon Glasgow, *History of the Glasgow Family*, original scan p. 2Names John, Robert and Hugh, in that order, as the three sons of Hugh Glasgow and Margaret McCullough. It gives a 1739 birth only for youngest son Hugh.Late family tradition supporting John's existence and asserted parents; it does not support John's profile dates or descendants.
WikiTree Glasgow-549, live profile checked 20 July 2026The biography uses the 1831 Dromain and Coltrim households as possible descendants but supplies no intermediate relational record.The 1831 households are later same-name people and cannot document this John's life or children.
John Glasgow's family Bible and 1847 letterJohn born 1767 used sons Adam, James, John and Arthur and second daughter Maria; the letter recalls Inishrush and carries news plausibly involving Adam-3902's son James.Strong evidence for the younger John's Inishrush identity and close kinship with Adam, but no statement naming this older John as father.
Public Glasgow Y-DNA projectKit N18544 is attributed to John born 1767. No displayed kit identifies a paper-trail male-line descendant of this profile or his traditional brothers.Cannot test or select this father. The uncited “Melanchthon branch” label found in an older WikiTree biography is not independently reproducible from the public table.
William Melanchthon Glasgow family history, p. 3Says this John's younger brother Hugh had a family farm near Portglenone by 1780.Stronger geographic continuity for the traditional sibling group, but no statement that this John remained there or had Adam and John as sons.

Working hypotheses and conflicts

John Glasgow was possible direct father, undistinguished from Robert Adam Glasgow

possible1 linked evidence item

Chronology and regional tradition work, but John-822's first son Adam points instead to an older Adam as paternal grandfather. No record names John-549's wife or child. Robert-550 is equally unproved.
