Ok, let's see if I can help with the first year just now.
1917:
Marsha Hunt (IMDb) actress - still alive as of March as per this BBC article about her, definitely won't die off grid.
Don Marion (IMDb) silent film actor - interesting case. Reported dead in a 2012 book (and several places give this as a death date) but Wikipedia says this is not correct and this article from Arizona (where he is now living) recognises him in their 32nd annual 'Salute to Centenarians' event. Nothing since that I can find so assume he's still alive. Can't find anything for the 33rd annual 'Salute to Centenarians' - probably cancelled because of the 'rona.
Daphne Courtney (IMDb) actress - South African-born actress in B-movies in the 30s and 40s. Married Scottish actor Hugh McDermott in 1936 in London (date found online and confirmed by Ancestry). Full name Daphne Ralda Courtenay-Hicks. Have found this record that would match for her husband's death in 1999 (also born 1917) in Droitwich, Worcestershire - no matching death for Daphne though. Still, it's a start?
Eleanor Hansen (IMDb) actress - American actress from Indiana, USA, roles in the 30s and early 40s only, mostly uncredited. Not turned much up on her, she disappears after the 40s and I don't have access to US records to trace marriage, etc.
Eddie Infante (IMDb) actor and director - Filipino actor with long list of credits from the 1930s up to 1995 (when he'd have been nearly 80). Nothing since and I can't find any mention of him anywhere on Google in either English or Spanish. Full name Jesus Eduardo Ferriol Infante.
Antonio Gradoli (IMDb) actor - Italian actor with credits from the 30s to the late 60s. Italian Wiki also lists him as alive. Also known as Anthony Gradwell - I think only in English dubs of European films? Another one who disappears without trace as far as I can see.
That wasn't much use really was it? It started so well, but I've not found anything definitively killing any of them but neither can I prove for sure that most of them are alive.
