Margaret Hartman (1832 - 1914)

The proposed relationship of Margaret Hartman as the mother of Joseph Henry Mixer and Edna Mixer is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a 3rd cousin, once removed relationship between TDH (a descendant of the Joseph Henry Mixer ancestral line) and WTD (a descendant of the Edna Mixer ancestral line) with 16.31 cM of shared DNA across 1 HIR segments.

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