If you use Family Tree Builder to build your tree, please read the following article:How do I add family members to the tree in Family Tree Builder?
To add family members to your online tree, use the ‘Add’ link on a person card in the tree.
Select the desired relation (son, daughter, mother, father, partner, etc.).
You can also choose to Edit details of this person, delete, add photos and more.
Use the ‘X’ button in the upper right hand corner of this screen to go back to the family tree without adding anyone.
Please note that if you created your tree in the Family Tree Builder and published it to your family site, you will have to add members in the Family Tree Builder and then re-publish the tree to the site, in order to update your tree.
