Ok Take a look at it now. What you had was ok, but what's there now follows the standard guidelines.
If you put your source information between <ref> and </ref>, it makes a nice footnote at the end, if you also add <references /> just after the == Sources == line. the <references /> tells the computer "Put the footnotes here."
Note: There didn't seem to be a fact to go with the 1861 census so its just a source without a sentence. Did it have something?
Notice also I turned the facts into simple sentences, so it becomes a narrative.
You can send me a message it you want me to check others.
