Thank you so much for the reply and the link to the map! That is incredibly fascinating about the mineral tramway! I'm very curious about what the dotted-dashed lines mean (also the notations R.H., C.R., Und., etc).
So I am wondering now if maybe they lived in a different place from these farm buildings. The 1851 census appears to say "Thornwell Hill" for the street/road but it has multiple families with that same location and the script is difficult for me to make out--maybe I'm wrong? At the top of the census page it is in the Township of Wentworth and Ecclesiastical District of Thorpe Hesley. My ancestors would not have been wealthy enough to have servants, and they were not farmers or servants themselves--they were nailers. If you or anyone is able to look, you might have a better idea of what it is actually saying. From ancestry, it is Yorkshire/Wentworth/1A (page 8 marked on top right corner of census, but page 9 on ancestry navigation window)
Unfortunately, I am completely uneducated about political boundaries in England, but if you suggest I move to the other forum I can do that.
Thanks again!
Susan
