The proposed relationship of G van Arragon as the father of D van Arragon and BVA is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a 2nd cousin, twice removed relationship between FR (a descendant of the BVA ancestral line) and EO2 (a descendant of the D van Arragon ancestral line) with a shared segment of 114.06 cM across 7 HIR segments.

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