If you're just looking for an existing connection, then you or the other person can find that out by clicking on the Find Relationship button on the others profile. For the other person to see your private profiles, you would need to extend to them a Family Group invite, which can be done on the actions tab of the person's profile.
You could try this: https://www.geni.com/family-tree/share
Or just have them join Geni and you can send them a family invite.
