The maternal relationship between Lacy Van Wagenen and her son
Charles Levan Davis is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant
Marsha Leen.
The segmental (via DNA segment triangulation) and total DNA shared between Marsha Leen and other confirmed descendants of
David Van Wagenen/
Julia Ann Provost is consistent with the expected ranges for their respective relationships. Since Marsha Leen descends from David Van Wagenen/Julia Ann Provost through Lacy Van Wagenen and her son Charles Levan Davis, the presence of significant shared DNA between Marsha Leen 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 Lacy Van Wagenen to Charles Levan Davis, and ultimately to Marsha Leen, confirming this direct ancestral connection through multiple generations.
