She had a (long-time) home in the same NJ township in which I lived for several years. I briefly worked for the building department, and any time she would call about anything, she was very nice and would never say “This is Celeste Holm” - she would always say “This is Mrs Addy”. At the time, she was married to character actor Wesley Addy - they were married from 1961 to his death in 1996.
I would see her occasionally in the local Shop-Rite; I always would smile and give a little nod, and she would nod back. I don’t know how many other townies knew her, but it was never “ZOMG IT’S CELESTE HOLM!” I think classic movie fans have a bit more tact 
One of her sons is Ted Nelson - the guy who coined the phrases hypertext and hypermedia in 1963 (!) and published them in 1965.
I am saddened at her passing - yet another elegant light from the Golden Age has been dimmed, and I fondly remember her as the Fairy Godmother in the 1960s TV version of Cinderella. Sadly, she was embroiled in a nasty estate battle with her sons over her current (now her widower) husband. She was living in reduced circumstances, although from most accounts very much loved and cared for. It’s always about the dough, ain’t it?
