Mary Burkhart

The maternal relationship between Mary Burkhart and her son Oliver Roberts is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MR2.

The segmental (via DNA segment triangulation) and total DNA shared between MR2 and other confirmed descendants of TJB/D is consistent with the expected ranges for their respective relationships. Since MR2 descends from TJB/D through Mary Burkhart and her son Oliver Roberts, the presence of significant shared DNA between MR2 and other known descendants of TJB/D validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple TJB/D through Mary Burkhart to Oliver Roberts, and ultimately to MR2, confirming this direct ancestral connection through multiple generations.
