If she was
living there in the 1871 (or other) census/es you might be able to narrow down the location by following the enumerstor’s route (written on page one of the census book).
Descriptions of routes can vary in amount of detail given, from just a general description of the area covered, to naming specific farms and sometimes owners.
If you need more detail than given on page one, make a note of the neighbouring addresses from the census to map out the route - then try to follow it on an old map. I recommend the NLS side by side maps. Once you find the approximate location, if the NLS map doesn't give enough detail, sometimes different maps from old-maps.co.uk are worth a look.
This method may or may not work to find a specific farm, depending on other factors. Let us know if you need any help with this, and give us her name and other details so we can find her on the censuses.
Regarding what she farmed ... knowing the location
might help us make an educated guess.
