The paternal relationship between Paul Leyton Humphrey and his daughter JKH is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JKH.

The segmental (via DNA segment triangulation) and total DNA shared between JKH and other confirmed descendants of TC/Frances Sinclair is consistent with the expected ranges for their respective relationships. Since JKH descends from TC/Frances Sinclair through Paul Leyton Humphrey and his daughter JKH, the presence of significant shared DNA between JKH and other known descendants of TC/Frances Sinclair validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple TC/Frances Sinclair through Paul Leyton Humphrey to JKH, and ultimately to JKH, confirming this direct ancestral connection through multiple generations.
