Paul,
Reference your post on 7th October ( Have you come across any Cant, Mitchell, Spink or Johnson links in your studies of Wickham St Paul or Gestingthorpe ? )
The only Johnson information I have relates to William Johnson who married Elizabeth Potter in Gestingthorpe on 16th June 1771. They had at least eleven children all born in Gestingthorpe - in date order William, Elizabeth, James,Judith Joseph 1780 (died 1 day old), Ruth, Phoebe, Hetty, Bathsheba, Milly and Potter.
I think the one with the most interest to you is Hetty who married James Cant of Wickham St Paul at Gestingthorpe on 19th May 1812 - witnesses were William Cant and Amelia Johnson.
It appears that James and Hetty went to live in nearby Pebmarsh. The 1851 census shows Hetty as a widow and described as a schoolmistress -they had at least two children Josiah and James.
Hope this is of interest
Mike
