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