Seems unusual for there to be 2 Sabina Fords of the same age in the same small village, maybe she was visiting and her mother put her down as well

That is what I think must have happened, Nessie.
I tried all sorts of spellings of her name in 1841 and only found the one I posted.
Incidentally, you were asking (by PM) about the unusual names - Sabina is a variation on Sabrina, the roman name for the river Severn: good views of that from Wotton!!
