The proposed relationship of Per Estensson as the father of Eric Pehrsson and Esten Pehrsson is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a 3rd cousin, twice removed relationship between VW (a descendant of the Esten Pehrsson ancestral line) and NAS (a descendant of the Eric Pehrsson ancestral line) with a shared segment of 70.75 cM across 4 HIR segments.

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