Hi Charlysue: Welcome to Rootschat.
I did a search for "Town Bottom" and Thornton and came up with 3,600 results. From those results, I eliminated Clayton (near Thornton); Temecula, California; Cape Town, South Africa; and the abbreviation "CO" for Colorado, because there apparently is a Thornton in Colorado. I was left with 43 results.
Only one of them mentioned Town Bottom, Thornton near Bradford. That was Your Archives, which is a website run by the U.K. National Archives. It lists street names for various registration districts in the U.K census. The link I'm posting here is for Bradford Registration District for the 1851 census. You will go to the page for streets beginning with the letter T.
Here's the link:
http://www.rootschat.com/links/0nvf/ If you scroll down until you reach Town Bottom, Thornton, you'll have the census reference and the folio numbers in which Town Bottom is enumerated. The second column heading is labeled Nearby Street. For Town Bottom in Thornton that nearby street is Thornton. That may mean Thornton Road.
If you search the 1851 census for the reference and folios that Town Bottom appears on, you should get the names of other streets near to or intersecting with Town Bottom. That should give you a better idea of where it is (or was).
Or maybe Linda (Danuslave), who originally posted the information will see this and explain it better than I can.
Hope this helps.
John
