The paternal relationship between Martin Crowley and his daughter EC is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant EM.

The segmental (via DNA segment triangulation) and total DNA shared between EM and other confirmed descendants of JC is consistent with the expected ranges for their respective relationships. Since EM descends from JC through Martin Crowley and his daughter EC, the presence of significant shared DNA between EM and other known descendants of JC validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA JC through Martin Crowley to EC, and ultimately to EM, confirming this direct ancestral connection through multiple generations.
