The proposed relationship of James Monroe Decamp as the father of
Dora Elizabeth Decamp and
Clinton George Decamp is supported by DNA evidence indicating shared ancestry within the family lines.
Specifically, DNA evidence confirms a 1st cousin, twice removed relationship between LMD (a descendant of the Clinton George Decamp ancestral line) and SE (a descendant of the Dora Elizabeth Decamp ancestral line) with 286.96 cM of shared DNA across 15 HIR segments.
This match is consistent with their placement within these shared ancestral branches.
