The maternal relationship between Hanora Sheehy and her daughter Ellen Tom Lenihan is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MF.

The segmental (via DNA segment triangulation) and total DNA shared between MF and other confirmed descendants of John Sheehy/Elizabeth Drury is consistent with the expected ranges for their respective relationships. Since MF descends from John Sheehy/Elizabeth Drury through Hanora Sheehy and her daughter Ellen Tom Lenihan, the presence of significant shared DNA between MF and other known descendants of John Sheehy/Elizabeth Drury validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple John Sheehy/Elizabeth Drury through Hanora Sheehy to Ellen Tom Lenihan, and ultimately to MF, confirming this direct ancestral connection through multiple generations.
