Kelly,
I do not use the Online Tree products at Ancestry, so I don't know what other Options you have to put your information online. In the
Family Tree Maker program, prior to 2008, there is a User Home Page option that I do use, and I an put anything on there I want.
You might look at what your other options are at Ancestry of putting your information online. GEDCOM does not appear to do what you want.
