The paternal relationship between Troy Sylvester Terry and his daughter KD is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant KD.

The segmental (via DNA segment triangulation) and total DNA shared between KD and other confirmed descendants of Whitson Pennington/Mary Chapman is consistent with the expected ranges for their respective relationships. Since KD descends from Whitson Pennington/Mary Chapman through Troy Sylvester Terry and his daughter KD, the presence of significant shared DNA between KD and other known descendants of Whitson Pennington/Mary Chapman validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Whitson Pennington/Mary Chapman through Troy Sylvester Terry to KD, and ultimately to KD, confirming this direct ancestral connection through multiple generations.
