The paternal relationship between John Thomazin BIRD and his daughter
Betsy BIRD is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DWA.
The segmental (via DNA segment triangulation) and total DNA shared between DWA and other confirmed descendants of
Joshua BIRD/
Mary Ann THOMAZIN is consistent with the expected ranges for their respective relationships. Since DWA descends from Joshua BIRD/Mary Ann THOMAZIN through John Thomazin BIRD and his daughter Betsy BIRD, the presence of significant shared DNA between DWA 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 John Thomazin BIRD to Betsy BIRD, and ultimately to DWA, confirming this direct ancestral connection through multiple generations.
