No, I don't think that is the Sarah I am looking for but thanks anyway. Sarah's birth year in the Censuses ranges from 1811 to 1817 but the place of birth, Folksworth, never changes. However there is nothing on line for Folksworth that I can find and it seems to vary between being in Huntingdonshire and in Northamptonshire, which makes where to look even more confusing.
