The maternal relationship between Rose Ellen LADD and her daughter
Mabel FRASER is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JAN.
The segmental (via DNA segment triangulation) and total DNA shared between JAN and other confirmed descendants of
Robert TWELVES/
Ann WILLIAMS is consistent with the expected ranges for their respective relationships. Since JAN descends from Robert TWELVES/Ann WILLIAMS through Rose Ellen LADD and her daughter Mabel FRASER, the presence of significant shared DNA between JAN and other known descendants of Robert TWELVES/Ann WILLIAMS validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Robert TWELVES/Ann WILLIAMS through Rose Ellen LADD to Mabel FRASER, and ultimately to JAN, confirming this direct ancestral connection through multiple generations.
