The paternal relationship between Arnold Roberts and his daughter ASR is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DG.

The segmental (via DNA segment triangulation) and total DNA shared between DG and other confirmed descendants of Patrick Flannery/Martha McGurk is consistent with the expected ranges for their respective relationships. Since DG descends from Patrick Flannery/Martha McGurk through Arnold Roberts and his daughter ASR, the presence of significant shared DNA between DG and other known descendants of Patrick Flannery/Martha McGurk validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Patrick Flannery/Martha McGurk through Arnold Roberts to ASR, and ultimately to DG, confirming this direct ancestral connection through multiple generations.
