The paternal relationship between James Gordon Tompkins and his daughter
Ona Mildred Tompkins is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MF.
The segmental (via DNA segment triangulation) and total DNA shared between MF and other confirmed descendants of
Abram Tompkins/
Mary Ann Eaton is consistent with the expected ranges for their respective relationships. Since MF descends from Abram Tompkins/Mary Ann Eaton through James Gordon Tompkins and his daughter Ona Mildred Tompkins, the presence of significant shared DNA between MF and other known descendants of Abram Tompkins/Mary Ann Eaton validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Abram Tompkins/Mary Ann Eaton through James Gordon Tompkins to Ona Mildred Tompkins, and ultimately to MF, confirming this direct ancestral connection through multiple generations.
