You are the Manager of all of the profiles you add to your tree. This means that you control the privacy of these profiles. You can choose to Share any profiles that you think may be of interest to other Geni users outside of your close family. Sharing a profile means that anyone can search for and view the entire profile. We suggest that you share any profile beyond your close relatives. At a minimum, you should share any significant profile such as a historical figure. This will help others users related to this person find them and share research with you.
