Hello Westy
The Edward Elphick who was buried at Chiddingly in 1818 was a miller and he passed over the business to his two sons Thomas and Richard in 1812, per an article in the Sussex Advertiser newspaper 26 October 1812. The Death Duties Register shows his executor was Thomas Elphick.
The Edward Elphick who married Hannah Bovis at Rye in 1759 was, per the marriage register transcript, a seaman, and a sojourner itp (a temporary resident in this parish). It appears he is the Edward bap Willingdon 1734 and looks unlikely that he is the miller Edward, who I think came from Arlington/Hellingly.
