Welcome! This forum has a treasure trove of great info – Scouters helping Scouters! Just a heads up, though - all content, information, and opinions shared on this forum are those of the author, not the BSA.
@MarkCorbett I was able to find a 3rd BSA member ID number for this user that I think has the correct name and DOB:
131359280
Please ask your local council to use their Registrar Tools to look up the user’s child (or children). In the Relationships section, he should be listed as parent only under BSA 131359280. He should be removed if listed as parent under any other BSA member numbers. Otherwise, his numbers might get switched at Recharter, and this could result in creating another Scoutbook account.
