The proposed relationship of Herbert Benjamin Noll as the father of Marjorie Ruth Noll and DN is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a great aunt / uncle relationship between KMC (a descendant of the Marjorie Ruth Noll ancestral line) and JB (a descendant of the DN ancestral line) with a shared segment of 764.70 cM across 33 HIR segments.

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