The paternal relationship between Edward Arthur ROBERTS and his DNA tested daughter Joan Patricia ROBERTS is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between Joan Patricia ROBERTS and other confirmed descendants of JH/MF is consistent with the expected ranges for their respective relationships. Since Joan Patricia ROBERTS descends from JH/MF through Edward Arthur ROBERTS, the presence of significant shared DNA between Joan Patricia ROBERTS and other known descendants of JH/MF validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple JH/MF through Edward Arthur ROBERTS to Joan Patricia ROBERTS, confirming this direct ancestral connection through multiple generations.
