[AccessD] Check for duplicate children in table

I need to see if an parents in a field named TargetPID in a table have
the same children in a field named sourceNAME. Any parent can have 1 to
10 children. I need some help on how to check if any parents have the
same children as another parent. No I did not pick the field names.
Thanks.
