Mary Geary (ABT 1811 - )

The maternal relationship between Mary Geary and her son John Barrett is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JJ.

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

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