Joan Murdoch (11 Mar 1917 - 23 May 1994)

The proposed relationship of Joan Murdoch as the mother of MEM and Judith Ann Maxwell is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a great aunt / uncle relationship between KZ (a descendant of the Judith Ann Maxwell ancestral line) and MKL (a descendant of the MEM ancestral line) with a shared segment of 982.10 cM across 38 HIR segments.

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