The proposed relationship of Abiah Leavitt as the mother of Clarissa Elizabeth Lewis, Albert Lucius Lewis and Cynthia Lewis is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a distant cousin relationship between MM (a descendant of the Albert Lucius Lewis ancestral line) and KC (a descendant of the Clarissa Elizabeth Lewis ancestral line) with a shared segment of 32.75 cM across 2 HIR segments.

It also confirms a distant cousin relationship between KC (a descendant of the Clarissa Elizabeth Lewis ancestral line) and LL2 (a descendant of the Cynthia Lewis ancestral line) with a shared segment of 29.04 cM across 2 HIR segments.

These matches are consistent with their placement within these shared ancestral branches.
