I've been experimenting with the "Your Family Tree" section of the Ancestry.com site. Ancestry will give you hints in the hopes that you have overlooked records and will allow you to attach images (and source information) directly to your database. This is nice.
My best option here would have been to check the "add as alternate" fact. While technically not inconsistent with the information I originally had, I do NOT want to indicate the census said something it did not. Adding an alternate fact would allow me to use the census as a source for Samuel's birth and track EXACTLY what it said.
