The proposed relationship of Ralph Edward Carpenter as the father of Dennis Owen Carpenter and TAC is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a great aunt / uncle relationship between JC (a descendant of the TAC ancestral line) and DC (a descendant of the Dennis Owen Carpenter ancestral line) with a shared segment of 963.76 cM across 27 HIR segments.

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