Currently I am on our narrowboat, with no Grimwade to check addresseses or dates , but would suggest that the following wills at the National Archive would be worth downloading
Will of William Abdy of Goldsmith Alms Houses Hackney Road , Middlesex 01 January 1835 PROB 11/1841
(maybe he fell on hard times or was an official ?)
Will of William Abdy, Silversmith of Oat Lane , City of London 15 September 1790 PROB 11/1195
(thats probably his father)
at
www.nationalarchives.gov.uk/documentsonlineWill cost you £3.50 per will but often gives glorious information.
Or nothing much.
If you do get either of these I'd appreciate a copy !
