John Joseph Geary (19 May 1879 - 21 Mar 1959)

The paternal relationship between John Joseph Geary and his daughter Mary Bridget Geary is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MFF.

The segmental (via DNA segment triangulation) and total DNA shared between MFF and other confirmed descendants of G is consistent with the expected ranges for their respective relationships. Since MFF descends from G through John Joseph Geary and his daughter Mary Bridget Geary, the presence of significant shared DNA between MFF and other known descendants of G validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA G through John Joseph Geary to Mary Bridget Geary, and ultimately to MFF, confirming this direct ancestral connection through multiple generations.
