Hi, I do this with all the married women in my tree. When you add information of a person (on the left) just add the maiden name where it says (surname now) and it will show up in your tree. On that same line I also add "Gt. Grandma" or "Gt. Grandpa" or GGG Gran, whatever you want to put but it must be on that line. Have a practise. Hope this has been helpful.
