This might be similar the "Double Cousin" post but I had better keep it separate.
I have a case of second cousins marrying (each other). As I enter the name of each second cousin as the spouse of the other in their respective profiles their names are duplicated in the index. I really don't see any way around this. Is it just something I have to accept. This is in AFT.
Heaven knows what FTM will make of it when I sync!
