The maternal relationship between Patricia Kathleen Stuart and her DNA tested daughter JW is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between JW and other confirmed descendants of
Joseph Asa Johnson/
Sarah Lucy Tobey is consistent with the expected ranges for their respective relationships. Since JW descends from Joseph Asa Johnson/Sarah Lucy Tobey through Patricia Kathleen Stuart, the presence of significant shared DNA between JW and other known descendants of Joseph Asa Johnson/Sarah Lucy Tobey validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Joseph Asa Johnson/Sarah Lucy Tobey through Patricia Kathleen Stuart to JW, confirming this direct ancestral connection through multiple generations.
