The proposed relationship of James Albertson as the father of William Robert Albertson and GJA is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a 3rd cousin, once removed relationship between SA (a descendant of the GJA ancestral line) and BM (a descendant of the William Robert Albertson ancestral line) with a shared segment of 15.74 cM across 1 HIR segments.

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