Children of David James McCartney & Margaret Ann Devore

Note: David James McCartney's g-g-grandson took the ftdna.com Y-111 DNA test in September 2016; the same Y-111 DNA test taken by the researcher four years earlier and processed at the same lab. Results indicated the researcher and David James McCartney's g-g-grandson's DNA matched with 85% certainty four generations back and with 98% certainty eight generations back. This genetic evidence clearly linked the researcher's ancestor Robert Isaac McCartney as a sibling of David James McCartney.

Furthermore, an Ann (Sanford) McCartney was residing with her son David James McCartney and family in the 1850 Federal Census of North Strabane Twp., Washington Co., PA.
