The maternal relationship between Marion Elizabeth Cain and her DNA tested daughter PKH is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between PKH and other confirmed descendants of
Bernard "barney" R Cain is consistent with the expected ranges for their respective relationships. Since PKH descends from Bernard "barney" R Cain through Marion Elizabeth Cain, the presence of significant shared DNA between PKH and other known descendants of Bernard "barney" R Cain validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA Bernard "barney" R Cain through Marion Elizabeth Cain to PKH, confirming this direct ancestral connection through multiple generations.
