The proposed relationship of Amy Palmer as the mother of Peter White and Catherine White is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a distant cousin relationship between KLF (a descendant of the Peter White ancestral line) and RW (a descendant of the Catherine White ancestral line) with a shared segment of 28.30 cM across 1 HIR segments.

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