Katharina Schellenberg (10 Feb 1805 - 10 Nov 1844)

The proposed relationship of Katharina Schellenberg as the mother of Franz Janzen and Johann Janzen is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a distant cousin relationship between JMP (a descendant of the Johann Janzen ancestral line) and TNP (a descendant of the Franz Janzen ancestral line) with a shared segment of 54.57 cM across 5 HIR segments.

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