The paternal relationship between William Hudson Campbell and his son PGC is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant ES.
The segmental (via DNA segment triangulation) and total DNA shared between ES and other confirmed descendants of TC/
Frances Sinclair is consistent with the expected ranges for their respective relationships. Since ES descends from TC/Frances Sinclair through William Hudson Campbell and his son PGC, the presence of significant shared DNA between ES 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 William Hudson Campbell to PGC, and ultimately to ES, confirming this direct ancestral connection through multiple generations.
