The maternal relationship between Rachel Francis Casey and her son
Edward Joseph Maloney is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant GD.
The segmental (via DNA segment triangulation) and total DNA shared between GD and other confirmed descendants of
Daniel Casey/
Margaret Donahue is consistent with the expected ranges for their respective relationships. Since GD descends from Daniel Casey/Margaret Donahue through Rachel Francis Casey and her son Edward Joseph Maloney, the presence of significant shared DNA between GD and other known descendants of Daniel Casey/Margaret Donahue validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Daniel Casey/Margaret Donahue through Rachel Francis Casey to Edward Joseph Maloney, and ultimately to GD, confirming this direct ancestral connection through multiple generations.
