The proposed relationship of Marie Eva Arnold as the mother of
Leoba Kramer and
Amor Amadus Kramer is supported by DNA evidence indicating shared ancestry within the family lines.
Specifically, DNA evidence confirms a 3rd cousin, once removed relationship between KMC (a descendant of the Leoba Kramer ancestral line) and AR (a descendant of the Amor Amadus Kramer ancestral line) with 106.46 cM of shared DNA across 4 HIR segments.
This match is consistent with their placement within these shared ancestral branches.
