William Knight Tourle, father of Judith is mentioned in the will of his brother John Verralls Tourle a resident of Ford Sussex at the time he wrote the will, proven Prerogative Court of Canterbury 21 May 1822. He was a very wealthy man, he must have been the eldest son and inherited everything from his father or he married very well.
* Its on ancestry it mentions his wife children, husband of daughter, cousins etc., very informative as to relationships.
William was to get 60 pounds per year for his natural life to be paid on Lady Day (25 March)and Michaelmas Day (29 September).
As William was buried in August 1840 it's possible the family still paid the September amount of 30 pounds. Her mother also deceased, so Judith who was still at home was able to use it and so put herself as Independent on 1841 census. Just speculation on my part, where money is concerned it usually divides families.
