The proposed relationship of David Perry as the father of William Wallace Perry and Palmer Perry is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a distant cousin relationship between MS (a descendant of the Palmer Perry ancestral line) and SRB (a descendant of the William Wallace Perry ancestral line) with a shared segment of 34.89 cM across 2 HIR segments.

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