The younger family connects Scotland and Ulster.
FT20271 gathers the tested lines behind several Scottish, Ulster and American family histories. Its early-modern age gives those later movements a common paternal context.
The genetic context
FT20271, FGC5690 and FT16542 form the supplied block. The common-ancestor estimate is 1583, with a reported range of 1387–1728. Five tests remain at this level and two share the younger FTE32242 branch.
The historical interpretation
The reported roots include County Antrim, Derry and Scotland. Different families can remain, move between Scotland and Ulster, or cross the Atlantic in later generations.
Think of a family expanding through several households rather than one traveller following every later route. The genetic node brings their histories into the same frame; individual papers can explain how religion, land, work and relatives shaped each movement.
Next research step: Place the older Kilwaughter lines with SNP tests and compare them with the known Antrim and Derry branches.

Alexander Glasgow
FT20271 is checked in the reference kit’s VCF/BED. Alexander’s line and James J’s line share DYS714=27 and GD 3 at Y-111; no shared downstream SNP is exposed.

Linked tested descendant line
Read the family evidence →James J Glasgow
The tester’s documented paternal line reaches James J. His father is still the working-tree question; the genetic pairing with Alexander does not choose between the two routes.

Descendant tests through William, John M. and James M. place FT20271 at or above Robert. The James M. branch alone carries the child SNP FTE32242.

The public 1950 census supplies the final public father–son bridge in this William branch; the living tester’s name is not included.
Documentary route: Virginia → Ohio
Documented tester continuation
Read the family evidence →John M Glasgow
The descendant remains basal FT20271, without FTE32242. The public early chain is supported; the final private continuation is labelled probable by the project.
