On re-reading this thread I find I disagree with post #27!
A child didn't necessarily become a potential charge on a parish simply because he/she was baptised in that parish. A legitimate child, and the wife, automatically took the father's/husband's parish of legal settlement irrespective of where the child was born or baptised. It was only an illegitimate child whose parish of settlement was its parish of birth (hence the desire of parish overseers to remove pregnant single women who weren't local back to their own parish, so that the child didn't become a liability for them)
I recently came across a case of a deserted wife and her two children, all born in Derby, being removed from Derby to Shillington, Beds, as that was the husband's parish of settlement. The children ended up in Ampthill Union workhouse and the mother disappeared off to America, where the children joined her nine years later!
