Thomas Michael Cassidy (1850 - 1932)

The paternal relationship between Thomas Michael Cassidy and his son John Bernard Cassidy is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JC.

The segmental (via DNA segment triangulation) and total DNA shared between JC and other confirmed descendants of Stephen CASSIDY/Catherine BRITTON is consistent with the expected ranges for their respective relationships. Since JC descends from Stephen CASSIDY/Catherine BRITTON through Thomas Michael Cassidy and his son John Bernard Cassidy, the presence of significant shared DNA between JC and other known descendants of Stephen CASSIDY/Catherine BRITTON validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Stephen CASSIDY/Catherine BRITTON through Thomas Michael Cassidy to John Bernard Cassidy, and ultimately to JC, confirming this direct ancestral connection through multiple generations.
