Although the parish church at Stoughton dates from the 11th Century, the surviving parish registers only date from 1671 i.e. the first parish register has not survived. So, if others have been able to research back to an earlier date, they must have used other resources. Given the type of family that you have described, perhaps wills and manorial records are likely sources? Best wishes, Marion Woolgar Bognor Regis, West Sussex
