No candidate met the minimum age, location or family-naming threshold.

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.

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.

Record-bearing passages

  • Biography John Glasgow was born in 1780 in County Londerry, Ireland. The farm he was born on was near Portglenone which is on County Antrim, so the farm must have been near the county line. His parents were Hugh Glasgow and Sally Blair. They immigrated to the United States in August of 1796, landing in New Castle, Delaware. John settled in Pennsylvania, briefly in York before relocating to Allegheny County around 1802. He met his wife, Peninnah Thomas at an Associate Reformed Presbyterian Church meeting after walking to the Fork of the Yough Find a Grave memorial page for John Glasgow (28 Apr 1780–28 Aug 1840), Find a Grave Memorial no. 23399455, citing Depreciation Lands Museum Cemetery, Pittsburgh, Allegheny County, Pennsylvania, USA ; Maintained by Deb Hayes-Wolfe (contributor 46811474); . They married around 1806 and relocated to Deer Township in Allegheny County. The 1810 Census finds him in Deer Township with his wife and children. He would farm there until his death in 1840. John is buried in Pine Creek Cemetery in Pittsburgh with Peninnah, who joined him in death in 1848.
  • The biographical entry on the cited Find-a-Grave memorial (thank-you to Deb Hayes-Wolfe) says that John walked to the "fork of the Yough." The name Yough is a local shorthand for the Youghiogheny River that is still used today. The "fork" is referring to where that river meets the Monongahela River at McKeesport, a few miles upstream from Pittsburgh. The Reformed Presbyterian Church has had a strong presence in the town of McKeesport since the end of the 18th century. From the description, it is very likely that John and Peninnah met in McKeesport. https://en.wikipedia.org/wiki/Youghiogheny_River https://en.wikipedia.org/wiki/Reformed_Presbyterian_churches Research Notes One family history account of unknown origin (https://www.wikitree.com/photo.php/f/f5/Glasgow-209.pdf) lists these children of John Glasgow and Penninah Thomas.

Research Notes

The Origin of the Glasgows in the British Isles

The name "Glasgow" is Scottish. We know that the Glasgows who came to America were Presbyterian. John's ancestors had been in County Tyrone, one of the nine counties of the Ulster Plantation at least since the mid-1600s. It is a virtual certainty that the Glasgow line came to be in northern Ireland as settlers from southern Scotland in the early 1600s, who were required to be English-speaking and Protestant to settle there. https://en.wikipedia.org/wiki/Plantation_of_Ulster A large number of the Scots-Irish immigrated to the United States in the late 1700s and early 1800s. They settled primarily in Pennsylvania, Virginia, and North Carolina. https://www.electricscotland.com/history/america/scots_irish.htm
