ah well all I can tell you is he had 4 children that I know of - Elizabeth born um... 1798ish to his first wife, Elizabeth (I think) and John, William and James born to his second wife, Martha (also of Witham parish, don't know her maiden name). John was born c1814, William born c1817 and James c1819 (probably 1820). My husband is descended from James. They were all born, and grew up in, Hatfield Peverel. Gregory died around 1840, I think.... I am going from memory here.... I do know that John, and William, were living in Hatfield Pev. in 1851 along with mum Martha. Or at least William was. James married Elizabeth McKenzie in 1844 in London. John's wife was also an Elizabeth. John moved to Little Badlow as his children were all born there. William married a...Jane I think?? James' only child was called Martha. John had a daughter Martha. William's wife was actually Margaret I think as his daughter was Jane. William at one time lived in Withyham, Sussex (1870's) then moved to Kent I think after James's death. James was the innkeeper at the Dorset Arms Inn at Withyham Sussex in the 1870's. I will check the details and edit this post if necessary.
