The proposed relationship of Oscar Fredericks as the father of HF, CF and MF is supported by DNA evidence indicating shared ancestry within the family lines.
Specifically, DNA evidence confirms a 1st cousin, once removed relationship between EV (a descendant of the HF ancestral line) and CW (a descendant of the CF ancestral line) with 371.17 cM of shared DNA across 18 HIR segments.
It also confirms a distant cousin relationship between CM (a descendant of the MF ancestral line) and EV (a descendant of the HF ancestral line) with 143.25 cM of shared DNA across 11 HIR segments.
These matches are consistent with their placement within these shared ancestral branches.
Further support for shared ancestry within the HF, CF and MF lines is provided by an additional 1 DNA confirmed relationships among other tested descendants tracing back to these lines.
