The proposed relationship of Eliza Muxlow as the mother of WA and SEA is supported by DNA evidence indicating shared ancestry within the family lines.
Specifically, DNA evidence confirms a great aunt / uncle relationship between JA (a descendant of the WA ancestral line) and DS (a descendant of the SEA ancestral line) with 715.68 cM of shared DNA across 26 HIR segments.
This match is consistent with their placement within these shared ancestral branches.
