Hi Doris first of all YES you can.
Make sure that you COPY your GEDCOM from Ancestry into a FOLDER on your PC.
You will now have to UPLOAD this to ( I see your NEW SITE) in Tribal Pages ..
Sign in as ADMINISTRATOR in TP and select EDIT you should see this ( SCREEN SHOT BELOW0 )
Click on UPLOAD GEDCOM and follow the INSTRUCTIONS from there.
Best of luck
Regards
Les
