Donald Warren Chapman (1927 - 1999)

The paternal relationship between Donald Warren Chapman and his DNA tested son BC is confirmed by the direct inheritance path of autosomal DNA.

The segmental (via DNA segment triangulation) and total DNA shared between BC and other confirmed descendants of James Chapman/Ruth Bertha Hammer is consistent with the expected ranges for their respective relationships. Since BC descends from James Chapman/Ruth Bertha Hammer through Donald Warren Chapman, the presence of significant shared DNA between BC and other known descendants of James Chapman/Ruth Bertha Hammer validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple James Chapman/Ruth Bertha Hammer through Donald Warren Chapman to BC, confirming this direct ancestral connection through multiple generations.
