John Geary (ABT 1861 - ABT 1939)

The paternal relationship between John Geary and his son JJG is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JO.

The segmental (via DNA segment triangulation) and total DNA shared between JO and other confirmed descendants of G is consistent with the expected ranges for their respective relationships. Since JO descends from G through John Geary and his son JJG, the presence of significant shared DNA between JO 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 Geary to JJG, and ultimately to JO, confirming this direct ancestral connection through multiple generations.
