The paternal relationship between Benton Mcmillian Henry and his daughter JMHC is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant EC.
The segmental (via DNA segment triangulation) and total DNA shared between EC and other confirmed descendants of
Preston S. Robinson/
Jane H. Jackson is consistent with the expected ranges for their respective relationships. Since EC descends from Preston S. Robinson/Jane H. Jackson through Benton Mcmillian Henry and his daughter JMHC, the presence of significant shared DNA between EC and other known descendants of Preston S. Robinson/Jane H. Jackson validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Preston S. Robinson/Jane H. Jackson through Benton Mcmillian Henry to JMHC, and ultimately to EC, confirming this direct ancestral connection through multiple generations.
