John Conde married Susannah Godfreay at Christchurch, Spitalfields, London in 1822. They lived in St. Annes, Limehouse.London. There was another Conde family in the area at the time: John Conde, brushmaker and his son Alfred Conde who married a Charlotte Perry. I do not think that they are connected unless it is further back in time.
So far we have not been able to trace John or Susannah futher back. Do the Conde family originate in Cornwall? Is the spelling changed from Cundy or Condy?
