The proposed relationship of Jacqueline Yvonne Porter as the mother of DL and CL is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a aunt / uncle relationship between TL (a descendant of the CL ancestral line) and DL with a shared segment of 2255.82 cM across 58 HIR segments.

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