Theresa Geary (14 Jun 1925 - 30 Jun 1984)

The maternal relationship between Theresa Geary and her son O 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 Theresa Geary and her son O, the presence of significant shared DNA between JO 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 Theresa Geary to O, and ultimately to JO, confirming this direct ancestral connection through multiple generations.
