jonw65 - I have been going through the probate records for anyone who died in Southwick around the 60's, 70's, 80's, 90's to see if I could find one with that address - but nothing so far - one ref that could be relevant in the London Gazette of someone who died in a Southwick Nursing home in 2014.
I agree those Worthing deaths could be relevant but the first doesn't seem to have left a will and the second is too late for there to be an address - annoying!
John - do you have any first names of people (not living) who might have lived there?
