A good find yourself Yorkslass.
I am intrigued by his first name. He spells it Barnard, it's either he writes it as he pronounces it or it is possibly a surname used as a first name. However I have found no Barnards married to Beckhams.
There is a Benjamin "Backham" from Aylsham marrying an Elizabeth Wells in Erpingham in 1792 and having a son Barnard Beckham baptised in Aylsham in 1798 and 1804. Benjamin is presumably the son of "Bernard" Beckham b in Aylsham about 1771
I have found some Peachments in Terrington St Clements, born to a Thomas Peachment who was married twice there and seems to have had several children, including an Elizabeth, but no Susan or Susanna.
