Sarah Rose

The proposed relationship of Sarah Rose as the mother of John Cessna and Jonathan Cessna is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a distant cousin relationship between EO (a descendant of the John Cessna ancestral line) and RC2 (a descendant of the Jonathan Cessna ancestral line) with a shared segment of 43.70 cM across 2 HIR segments.

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