The maternal relationship between Julia Ann Watson and her daughter Mary Jane Stonecipher is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MC.

The segmental (via DNA segment triangulation) and total DNA shared between MC and other confirmed descendants of Henry Watson/Sarah is consistent with the expected ranges for their respective relationships. Since MC descends from Henry Watson/Sarah through Julia Ann Watson and her daughter Mary Jane Stonecipher, the presence of significant shared DNA between MC and other known descendants of Henry Watson/Sarah validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Henry Watson/Sarah through Julia Ann Watson to Mary Jane Stonecipher, and ultimately to MC, confirming this direct ancestral connection through multiple generations.
