The maternal relationship between Ruth Elendor Pennington and her son John Whitson Tucker is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant LT.

The segmental (via DNA segment triangulation) and total DNA shared between LT and other confirmed descendants of Whitson Pennington/Mary Chapman is consistent with the expected ranges for their respective relationships. Since LT descends from Whitson Pennington/Mary Chapman through Ruth Elendor Pennington and her son John Whitson Tucker, the presence of significant shared DNA between LT 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 Ruth Elendor Pennington to John Whitson Tucker, and ultimately to LT, confirming this direct ancestral connection through multiple generations.
