Sub-Groups of GFG2
Sub-Groups are formed when individual lineages have ties to a specific Guthrie Family Group, but the Y-DNA results in a genetic mismatch. These may be the result of adoptions, false paternity, feudal law or other causal events.
Guthrie Family Group 2B
According to the theory of ‘American Guthrie and Allied Families’ author, Rev. Laurence R. Guthrie, the family of Thomas Guthrie Sr. 1744-1837 & Mildred Howell belongs to GFG2A-Branch B. Thomas is supposed to be one of the sons of Robert Guthrie and his Darlington wife. However, two close cousins who descend from Thomas & Mildred’s eldest son, Thomas Guthrie, are genetic mismatched to the rest of GFG2A. It could be that the Causal Event is a much closer common ancestor to them, which would mean the rest of the Guthrie-Howell line should match its original group. It could also be that this mismatch is a sign common to the remainder of the line. We need at least 1 – 2 more Guthrie-Howell descendants to discover the truth.
Guthrie Family Group 2C
Descendants of Robert Guthrie 1752PA-1815OH & Elizabeth Jane Caldwell have a similar story. Robert is supposed to be one of the sons of GFG2A – Branch I’s James Guthrie and his Bissell wife. Another theory with little substance behind it other than a regional connection in Pennsylvania. We have only one Y-DNA participant from this lineage. While it might be easy to conclude he is a solitary genetic mismatch, his autosomal DNA matches to people who descend from the Guthrie-Caldwell line are significant. It appears that the genetic mismatch likely affects the entire Guthrie-Caldwell line. Still, we need at least 1 more descendant to prove that theory.
Guthrie Family Group 2D
This is a genetic mismatch involving a Guthrie-Gilkeson descendant. Another participant with connections to an earlier generation matches GFG2A.
Guthrie Family Group 2E
Project participants who descend from two different sons of John Guthrie 1781-1869 & Mary ‘Polly’ Rylee are genetic mismatches to parent group GFG2A-Branch K. They do match each other, which suggests that John himself was probably the original GFG2E mismatch. No documentation of an adoption has been found, but that is one potential reason, along with false paternity, for such a mismatch.
Guthrie Family Group 2F
This participant’s line is also historically traceable back to John Guthrie 1781-1869 & Mary ‘Polly’ Rylee. It does not match the original YDNA of GFG2A nor the GFG2E genetic profile. This shows two genetic mismatches within the same family line. In this case, the paper trail leads from Branch K to GFG2E to GFG2F. The genetic mismatch between GFG2E and GFG2F could have occurred any time after the generation of John Barney Guthrie (1816-1868).
Guthrie Family Group 2G
Branch K is just full of genetic surprises. Once again, we start with the son of Robert & Betsy Guttery/Guthrie of SC and GA. Their son John Guthrie 1781-1869 & Mary ‘Polly’ Rylee have another descendant with a genetic mismatch. The participant does not match John Guthrie’s GFG2E profile, nor does he match GFG2F. This genetic mismatch could have occurred with the birth of their son Leroy ‘Lee’ Guthrie or in any subsequent generation.
