The maternal relationship between Margaret Mary Rose and her son LC is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant LC.

The segmental (via DNA segment triangulation) and total DNA shared between LC and other confirmed descendants of Edward Ned Skehans/Johanna King is consistent with the expected ranges for their respective relationships. Since LC descends from Edward Ned Skehans/Johanna King through Margaret Mary Rose and her son LC, the presence of significant shared DNA between LC and other known descendants of Edward Ned Skehans/Johanna King validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Edward Ned Skehans/Johanna King through Margaret Mary Rose to LC, and ultimately to LC, confirming this direct ancestral connection through multiple generations.
