The proposed relationship of Magaretha Dyck as the mother of
Peter Dyck,
Jacob Dyck and
Maria Dyck is supported by DNA evidence indicating shared ancestry within the family lines.
Specifically, DNA evidence confirms a distant cousin relationship between TCF (a descendant of the Jacob Dyck ancestral line) and JW (a descendant of the Peter Dyck ancestral line) with 82.30 cM of shared DNA across 5 HIR segments.
It also confirms a distant cousin relationship between JH (a descendant of the Maria Dyck ancestral line) and JW (a descendant of the Peter Dyck ancestral line) with 63.30 cM of shared DNA across 5 HIR segments.
These matches are consistent with their placement within these shared ancestral branches.
