1) Do you have a tree today
2) What software do you use
3) Can you export the family tree to Gedcom?
Yes then you can import it
But lesson learned is that often you get better quality by adding the tree manually
Once you've connected you're imported gedcom to you, a three generation tree will be on your Nav Home Page. (see Drop down Menus, upper right hand corner, under My WikiTree.)
Also when on your own profile page. Click Family Tree and Genealogy Tools and you will see a graphic representation of your branch of the Wikitree.
Check your Watchlist (also accessed by the drop down menus under My Wikitree) Find your parents and connect them to you. Or if that couple Dorothy and Roland are you're grandparents, put a link to them on your profile
Ellen, you've uploaded your Gedcom, but you have a few more steps before you're gedcom is imported.
You're gedcom summary is here. You should have gotten an email, (sometimes they end up in spam folders) It says it needs to be approved by you.
Here's the report itself.
You need to read and follow the instructions - Before Importing a Gedcom
