Thanks for your message ref William and Susan. I do know some about James and his descendents (The boys all became doctors I think??) although my family is descended from Henry, James's older brother. Please let me know anything more!
Further back is very difficult to trace, however I have some info, including both William and Susan's parents. Don't, however, be persuaded by the IGI which has a whole load of erroneous entries on both families.
William and Susan BTW are both buried at Gunton just south of Lowestoft.
