I would like to change the father of my dad. He was born from an unmarried couple and then my grandma married his current husband and had 2 children. Right now, I can only set one father for the 3 of them. I see your answer to:
Goto the child you want to move
Click EDIT -> PARENTS -> DETACH FROM PARENTS
(The child and their descendants will then be orphaned)
Click EDIT -> PARENTS -> ATTACH PARENTS and select the correct parents from the list displayed
but i can't find the "PARENTS" option in the edit box
