Anyway. I think I'm excessively footnoting. Do you footnote only when you quote and use someone's idea or opinion but not with facts?
You should aim to show off research as much as possible.
'Facts'
That being said, it depends how well-known the fact is.
If you're talking about Columbus' arrival in South America, you would not need to footnote 'Columbus arrived in the Americas in 1492.'.
If you would not know the fact before doing research, you should cite from where you got it. For example 'Columbus' first voyage brought with it horses, previously never seen in the Americas.' would have to be cited.
However, if you are unsure, there's no harm in over-citing. Since you're using footnotes, over-citation doesn't really look messy or a hassle (like it can with in-text citation).
Better safe than sorry. Technically, you should cite a fact whenever you take it from someone else, but the 'well-known' test is a good one, imo.
Theory/opinion
You need to cite all opinions/theories. Even if a theory is pretty well-accepted or comes towards being a 'fact', you should still cite where you found it, or, better yet, find who said it first.
