The proposed relationship of Peggy Hargreaves as the mother of Henry Hindle and Betsy Hindle is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a distant cousin relationship between WJ (a descendant of the Betsy Hindle ancestral line) and JR (a descendant of the Henry Hindle ancestral line) with a shared segment of 66.42 cM across 3 HIR segments.

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