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