I did a mistake with my third great grandfather believing he was born in Banyoles, Catalunya, and therefore I followed building his family branch. But I was wrong, my true third grandfather was born in Igualada, Catalunya, he was someone else. There are hundreds of "relatives" that I put wrongly in the tree. Is there any posibility of removing him without having to remove all his ancestors and relatives?
