The proposed relationship of Raymond Nathaniel Donley as the father of Hilda Marie Donley Schreick and Ray Mike Donley is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a 1st cousin, twice removed relationship between PCD (a descendant of the Ray Mike Donley ancestral line) and HL (a descendant of the Hilda Marie Donley Schreick ancestral line) with a shared segment of 518.47 cM across 17 HIR segments.

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