The paternal relationship between Alfred Raphael and his son Alfredo Rafael Roffiel Valencia is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant RARDR.

The segmental (via DNA segment triangulation) and total DNA shared between RARDR and other confirmed descendants of Ralph Phillip Raphael is consistent with the expected ranges for their respective relationships. Since RARDR descends from Ralph Phillip Raphael through Alfred Raphael and his son Alfredo Rafael Roffiel Valencia, the presence of significant shared DNA between RARDR and other known descendants of Ralph Phillip Raphael validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA Ralph Phillip Raphael through Alfred Raphael to Alfredo Rafael Roffiel Valencia, and ultimately to RARDR, confirming this direct ancestral connection through multiple generations.
