Will a family in the Lead File be found by Jackrabbit's family duplicate detection when they re-register?

Families located in your Lead File are not searched in the duplicate detection. If a family that you have archived to the Lead File registers again with you online, Jackrabbit will not detect them as a duplicate and a new family record will be created. A user with the Merge Families/Accounts permission can merge the families once the lead file record is restored to your main database.
