I have now found out that my "grandfather" married to a woman who already was mother to my father. I have already made him a father to my father. How do I change it easily without deleting my father with all his sons and daughters and so on?
Thank you for a very quick answer. I hope I wiltl be informed when it is possible.to change the tree the way i informed you about. The tree is growing and people sometimes inform about relations which later will be found not exactly true.
