Question re purported death of actress Mary Gregory

Just wondering -- not just me the whole gang at TAPATALK (https://www.tapatalk.com/groups/twilightzoneworfr/mary-gregory-the-controversy-continues-t4740.html) -- about the purported death in 2018 of actress Mary Gregory (https://www.imdb.com/name/nm0339889/?ref_=nv_sr_1?ref_=nv_sr_1) -- not to be confused with actress Mary Ethel Gregory, a completely different actress (1925-2004)). IMDb gives date of death of Mary Gregory as January 8, 2018 (https://www.imdb.com/list/ls021061636).

However, I have, naturalIy, been unable to find any site online, aside from IMDb, to cite the actress's death. There are, of course, other American women with the same forename and surname who died in 2018 but none bear any similarity to the actress (except https://www.dignitymemorial.com/fr-ca/obituaries/newhall-ca/mary-jane-gregory-5972677  -- this Mary Gregory, who died in 2014, looks the most like the actress but I doubt it's her). 

Yours.
