I have made a family tree and my wife has made an account. I want to add her ID to my tree but I have no idea how to. Can anyone help?
Records of living people created by living people are ONLY visible by the person who created it. You will have to create your own record of your wife and she will have to create one for you. Yes, there will be duplicate records of both of you. The only records you can jointly see are deceased people. So make sure your records link back to the lowest level of deceased ancestors (your parents or grandparents?) as well as hers, and then you can work collaboratively on those records.
Thank you very much!
