The paternal relationship between Bernard Edward Thompkins and his daughter RT is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant RT.

The segmental (via DNA segment triangulation) and total DNA shared between RT and other confirmed descendants of Isaac Sanford Smith/Mary Taylor is consistent with the expected ranges for their respective relationships. Since RT descends from Isaac Sanford Smith/Mary Taylor through Bernard Edward Thompkins and his daughter RT, the presence of significant shared DNA between RT and other known descendants of Isaac Sanford Smith/Mary Taylor validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Isaac Sanford Smith/Mary Taylor through Bernard Edward Thompkins to RT, and ultimately to RT, confirming this direct ancestral connection through multiple generations.
