Many, many thanks John. That information is brilliant. Do you have access to marriages in Cardington by any chance ? After Frances Fowler died, her widower, Richard Fowler, remarried a lady called Elizabeth. If this happened in Cardington, it would have been between the death of Frances in 1817 and the birth of a son, James, in 1819 - by which time the family had moved to Great Wilbraham. Again, many thanks for your help.
Very gratefully,
Jenny
