How to remove duplicate names from the family list or member list
The only users who can remove/merge duplicate names in the Family list or Member list are diocese users.
Provide the duplicates for them via email and request they merge the duplicates. Make sure you indicate the MASTER family, which is the family you want to merge the duplicate into.
So, if Michael is a member with his parents and also the Husband of his own family, you want to merge him INTO the MASTER account, the account where he is the husband.
This is recommended over deleting because you can lose data if you delete a member or family that is duplicated. Merges are highly recommended to maintain the integrity of the parishioners' history at your church.
