Baby name too old-timey?

So basically im having a baby girl in december and we were really struggling to choose a name. Eventually the name Susanna-Rose came up and i fell in love. Its girly, feminine and can be shortened to nicknames. I told my friend that we were considering calling baby girl “Susanna-Rose” and she said its a lovely name but its a little bit too old-timey and old fashioned.

I dont want to name my baby that if people think of an old lady when they hear the name. What do you think? Is it too old or suitable?
