I immediately think of
Ingrid Bergman and old Hollywood glamour. I wouldn't use it, I think it's too harsh and cold. But I would love to see it on someone else! I met a nice young
Ingrid a few years ago, she made me like the name. Apart from that it is rather dated in Austria, there are many older women named this, aged 50-70.
I can't think of any nicknames. It really is a no-nickname name.
