The proposed relationship of Sarah Taylor as the mother of Robert Webb and JF is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a distant cousin relationship between PR (a descendant of the JF ancestral line) and LC (a descendant of the Robert Webb ancestral line) with a shared segment of 70.21 cM across 4 HIR segments.

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