The proposed relationship of William FOX as the father of Annie Maria Fox and Louisa FOX is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a distant cousin relationship between JA (a descendant of the Louisa FOX ancestral line) and DC (a descendant of the Annie Maria Fox ancestral line) with a shared segment of 27.96 cM across 2 HIR segments.

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