The maternal relationship between Lettie Van Wagenen and her son
David Carl Bronson is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant AB.
The segmental (via DNA segment triangulation) and total DNA shared between AB and other confirmed descendants of
David Van Wagenen/
Julia Ann Provost is consistent with the expected ranges for their respective relationships. Since AB descends from David Van Wagenen/Julia Ann Provost through Lettie Van Wagenen and her son David Carl Bronson, the presence of significant shared DNA between AB and other known descendants of David Van Wagenen/Julia Ann Provost validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple David Van Wagenen/Julia Ann Provost through Lettie Van Wagenen to David Carl Bronson, and ultimately to AB, confirming this direct ancestral connection through multiple generations.
