Hi Deetot: Thanks for your reply. I think it settles the question.
But as a footnote to the search: Last week I read the descriptions of some of the 1861, 1871, and 1881 census enumeration districts in Thornton. I wrote a reply to this thread the other day about Market Street's probably being Main Street, but I decided not to post it because I could not get a definitive answer. The enumeration district descriptions that I read used the phrase "the main street" when describing the boundaries of the district in question. "Main Street," the proper noun, was not used in the descriptions. It was only used on the actual census pages themselves. And it was almost impossible to figure out where streets actually were just from reading a description of the borders of the enumeration district.
The big surprise is that Main Street is not the only problematic street name in Thornton. Some time after 1861 there seems to have been a renaming of streets there. How many new or renamed streets there were, I'm not sure. But I did find Commercial St. and Industry St., both of which should have been near Market Street, what is now Thornton Road (New Road in 1871), and Green Lane.
The 1861 census had Rose Cottage, New Road Side, Old Mill Yard, for example. By 1871 those names were gone.
Searching an online map just now, I can't find Commercial St. or Industry St. And Green Lane seems not to be there either.
