The paternal relationship between Desmond Dennis McManus and his daughter AM is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant AM.

The segmental (via DNA segment triangulation) and total DNA shared between AM and other confirmed descendants of BM/AS is consistent with the expected ranges for their respective relationships. Since AM descends from BM/AS through Desmond Dennis McManus and his daughter AM, the presence of significant shared DNA between AM and other known descendants of BM/AS validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple BM/AS through Desmond Dennis McManus to AM, and ultimately to AM, confirming this direct ancestral connection through multiple generations.
