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