Bridget Lyden (ABT 1881 - ABT 1948)

The maternal relationship between Bridget Lyden and her daughter Mary Bridget Geary is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MFF.

The segmental (via DNA segment triangulation) and total DNA shared between MFF and other confirmed descendants of James Lyden/Mary Mongan is consistent with the expected ranges for their respective relationships. Since MFF descends from James Lyden/Mary Mongan through Bridget Lyden and her daughter Mary Bridget Geary, the presence of significant shared DNA between MFF and other known descendants of James Lyden/Mary Mongan validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple James Lyden/Mary Mongan through Bridget Lyden to Mary Bridget Geary, and ultimately to MFF, confirming this direct ancestral connection through multiple generations.
