Sometimes it helps to just check out the process steps and see how they work before you get started.
At the top of your Profile page, click the EDIT tab and see your full profile page. There you will see all the details you can add to your own profile and all the buttons and links to add/edit parents, siblings, spouses etc.
Click on any one of the add/edit links - and this will bring up the detail page showing all the entries that can be made at once on a Profile – dates, locations, sources etc.
For example, once you add both your parents, you can add your siblings from your own page or the page of either of your parents. And once you add a sibling – you can add more siblings from his/her page, your page, your mom’s page or your dad’s page. It doesn’t matter which way you do it, but I found that just being consistent helped me keep things straight! So eventually – I learned once I had a pair of spouses entered – it was easier for me to enter all the children from the mothers’ page, and check the box at the bottom that says [xxxx is the other parent].
Those edit buttons also let you remove your mistakes. Once you add your parents, click the edit button on one, and scroll down to the bottom of the page that comes up and you will see choices in the boxes, to add an additional spouse or just remove the previous spouse if it was entered in error.
Always pay attention to the boxes at the bottom that you have the option of checking.
Make sure you hit the SAVE CHANGES button on the EDIT page when you’re done (I sometimes forgot and then had to enter all over!
