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