Nancy Coats (12 Jun 1832 - 25 Jul 1905)

The maternal relationship between Nancy Coats and her daughter Louisa Jane Barr is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant RLB.

The segmental (via DNA segment triangulation) and total DNA shared between RLB and other confirmed descendants of Samuel Rudy/Salome Sally McGuire is consistent with the expected ranges for their respective relationships. Since RLB descends from Samuel Rudy/Salome Sally McGuire through Nancy Coats and her daughter Louisa Jane Barr, the presence of significant shared DNA between RLB and other known descendants of Samuel Rudy/Salome Sally McGuire validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Samuel Rudy/Salome Sally McGuire through Nancy Coats to Louisa Jane Barr, and ultimately to RLB, confirming this direct ancestral connection through multiple generations.
