Sub-Groups of GFG4

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.


Two participants who descend from Thomas Guthrey & Sarah Oakes’ son John Guthrey (b.1759) are genetic mismatches for the rest of GFG4. The genetic mismatch occurred sometime between John Guthrey’s generation and that of his great-grandson, Marion Francis Guthrie (b.1876).
