Alvina Wilke

The proposed relationship of Alvina Wilke as the mother of ELMWH and LH is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a 2nd cousin, once removed relationship between DH (a descendant of the LH ancestral line) and DRH (a descendant of the ELMWH ancestral line) with a shared segment of 148.75 cM across 7 HIR segments.

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