The maternal relationship between Elsie M Perry and her 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 David Perry/Martha Hamilton is consistent with the expected ranges for their respective relationships. Since SRB descends from David Perry/Martha Hamilton through Elsie M Perry and her son Alvin V Boylan, the presence of significant shared DNA between SRB and other known descendants of David Perry/Martha Hamilton validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple David Perry/Martha Hamilton through Elsie M Perry to Alvin V Boylan, and ultimately to SRB, confirming this direct ancestral connection through multiple generations.
