DNA
Every haplogroup branch this tree knows, explained once. A DNA result is recorded on one person — the tester, or the ancestor a testing project lists the kit under — and every relative on the same father-to-son (Y-DNA) or mother-to-child (mtDNA) line inherits it on their own page. 2 results recorded.
Y-DNA
- R-M222 2 The large "north-west Irish" branch of R1b (below DF49 and L21), strongly associated with Donegal, Derry and Tyrone and with Highland and Hebridean Scotland; the root of everything the North Uist Ferguson project records.
- Z2959 2 First step below M222 on the North Uist Ferguson line (FamilyTreeDNA path R-M222 > Z2959 > S658 > DF104 > DF105 > DF85 > S673 > BY25946 > FT94064).
- S658 2 Intermediate SNP below Z2959 on the M222 line, as ordered on the Ferguson - North Uist project page.
- DF104 2 Intermediate SNP below S658 on the M222 line.
- DF105 2 A major M222 subclade below DF104; the level at which many Ulster and west-Scottish lineages separate.
- DF85 2 Subclade of DF105; the Fergus(s)on Surname Project heads the North Uist section "R-M222 >> DF85 > S673 >> FT94064".
- S673 2 Subclade of DF85 that carries the North Uist Ferguson lineage and its neighbours. The deepest level FamilyTreeDNA's single-SNP tests reach: kit 680865 (William J Ferguson 1872-1927, lead only) is confirmed to here and no further.
- BY25946 2 Big Y branch below S673, above FT94064.
- FT94064 2 The branch shared by the North Uist Ferguson lineage (FT93868) and a pre-surname Boyd line (FTD49564, kit 803176, Thomas Boyd c.1710 Northern Ireland). The stray "R-M222 >> S673 >> FT94064" text that used to sit on several Ferguson birth events referred to this branch.
- FT93868 2 Terminal branch of "North Uist Lineage #1" in the Ferguson - North Uist Y-DNA Project: three Big Y-700 kits whose declared ancestors are John Ferguson b. 1774 (kit 457027), Neil Ferguson b. 1789 North Uist d. 1866 (kit N234513) and Murdoch McLea 1766 (kit 194971). Everyone on John's and Neil's father-to-son lines carries it.
- FTD49564 Sister branch of FT93868 under FT94064 - the project's "1b. Pre-surname connection to North Uist #1": kit 803176, declared ancestor Thomas Boyd c.1710, Northern Ireland. One step removed from the Ferguson line; the common ancestor predates the surnames. No Boyd is recorded in this tree - the connection lives here and on the kit's source row.
