Hi Phillip, click here for the help pages for adding family.
Adding Family by Connecting Existing Profiles
If a profile of your family member already exists on WikiTree ... great! :-)
Don't create a duplicate. WikiTree is all about collaboration. We are creating a single family tree with one profile for every person. Duplicate profiles defeat the purpose of WikiTree. (If you accidentally create a duplicate, merge them.)
To edit the relationships of an existing profile you will need to be on the profile's Trusted List unless it's Open.
You will see a form to send a Trusted List request on the profile. In your request, be sure to let the Profile Manager know your relationship. For example, you might say "[This profile] is my great-grandfather, through his son John."
Once you're on the Trusted List you can add the profile as a family member using their WikiTree ID. You enter this at the top of the form for adding a family member. For more details on connecting existing profiles, see Editing Family Relationships.
If the Profile Manager doesn't respond, see Unresponsive Profile Managers.
