The maternal relationship between Martha Ann Van Horn and her daughter
Cora Kessinger is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JPS.
The segmental (via DNA segment triangulation) and total DNA shared between JPS and other confirmed descendants of
Francis Read Van Horn is consistent with the expected ranges for their respective relationships. Since JPS descends from Francis Read Van Horn through Martha Ann Van Horn and her daughter Cora Kessinger, the presence of significant shared DNA between JPS and other known descendants of Francis Read Van Horn validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA Francis Read Van Horn through Martha Ann Van Horn to Cora Kessinger, and ultimately to JPS, confirming this direct ancestral connection through multiple generations.
