The proposed relationship of Bertha Haut as the mother of Leo Schultz and Alvin Schultz is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a 1st cousin, twice removed relationship between FS (a descendant of the Alvin Schultz ancestral line) and LA (a descendant of the Leo Schultz ancestral line) with a shared segment of 209.63 cM .

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