the program should tell us right away that we are entering the same person in our tree.
did a research on that person for nothing, it was the same person from a month ago
my grandfather 's uncle on my mother's side had a daughter who's daughter married my dad's half sister.
the program should ask ''same person '' and we would have the choice to say ''yes or no''
if yes, then link us to the earlier entry or put a symbol beside it so we wouldn't have to enter more data on the same person
