The proposed relationship of Elizabeth Thompson as the mother of
Amelia Shephard and
Emma Shephard is supported by DNA evidence indicating shared ancestry within the family lines.
Specifically, DNA evidence confirms a 2nd cousin, twice removed relationship between JS (a descendant of the Amelia Shephard ancestral line) and EL (a descendant of the Emma Shephard ancestral line) with 80.43 cM of shared DNA across 4 HIR segments.
This match is consistent with their placement within these shared ancestral branches.
