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.
@Matt.Johnson For the second parent (with “Do Not Use” in the last name) the parent’s registration history and User Relationships are under BSA member number 137276556.
Your council Registrar will want to remove those User Relationships under that number, and add them to the other number.
