This is just a suggestion and I hope the developers see it. Could there be a fact titled "Relationship"? This would be helpful to designate what the persons relationship to the owner is. For instance, I just recently found some second and third cousins. It would make things a lot easier if, when you call up a person out of the database it would have an entry for relationship and you could enter 1st Cousin, 3rd Cousin etc..
Any thoughts or inputs are welcomed.
