The proposed relationship of Ralph Phillip Raphael as the father of Henry Lewis Raphael and George C. Raphael is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a 3rd cousin, once removed relationship between DH (a descendant of the Henry Lewis Raphael ancestral line) and RARDR (a descendant of the George C. Raphael ancestral line) with a shared segment of 33.88 cM across 3 HIR segments.

This match is consistent with their placement within these shared ancestral branches.
