The maternal relationship between Eva Alice Tucker and her son RRS is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant LR.

The segmental (via DNA segment triangulation) and total DNA shared between LR and other confirmed descendants of Whitson Pennington/Mary Chapman is consistent with the expected ranges for their respective relationships. Since LR descends from Whitson Pennington/Mary Chapman through Eva Alice Tucker and her son RRS, the presence of significant shared DNA between LR and other known descendants of Whitson Pennington/Mary Chapman validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Whitson Pennington/Mary Chapman through Eva Alice Tucker to RRS, and ultimately to LR, confirming this direct ancestral connection through multiple generations.
