The paternal relationship between Gilbert Merrill Titcomb and his daughter LK is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant LK.

The segmental (via DNA segment triangulation) and total DNA shared between LK and other confirmed descendants of Howard Chessman Titcomb/Lorena Stubbs is consistent with the expected ranges for their respective relationships. Since LK descends from Howard Chessman Titcomb/Lorena Stubbs through Gilbert Merrill Titcomb and his daughter LK, the presence of significant shared DNA between LK and other known descendants of Howard Chessman Titcomb/Lorena Stubbs validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Howard Chessman Titcomb/Lorena Stubbs through Gilbert Merrill Titcomb to LK, and ultimately to LK, confirming this direct ancestral connection through multiple generations.
