The paternal relationship between Alvin Vernett Boylan and his son Alvin V Boylan is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant SRB.

The segmental (via DNA segment triangulation) and total DNA shared between SRB and other confirmed descendants of Isaac Johnson/Rachel Catherine Robinson is consistent with the expected ranges for their respective relationships. Since SRB descends from Isaac Johnson/Rachel Catherine Robinson through Alvin Vernett Boylan and his son Alvin V Boylan, the presence of significant shared DNA between SRB and other known descendants of Isaac Johnson/Rachel Catherine Robinson validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Isaac Johnson/Rachel Catherine Robinson through Alvin Vernett Boylan to Alvin V Boylan, and ultimately to SRB, confirming this direct ancestral connection through multiple generations.
