The proposed relationship of Martha Amelia Carner as the mother of Zoe Ellen Rorabaugh and Inez Leila Rorabaugh is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a 1st cousin, twice removed relationship between CJL (a descendant of the Inez Leila Rorabaugh ancestral line) and SK (a descendant of the Zoe Ellen Rorabaugh ancestral line) with a shared segment of 216.24 cM across 8 HIR segments.

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