No, it's a personal association that would be completely irrelevant to anyone else. It's a couple I know quite closely whose names are variants of Sylvie and Alba. Either one alone is going to look like I've named my kid after one of them, which I wouldn't be, both were favourites before I even met them, but to use both would be way too much, and everyone would know it.
So unless you know the same couple I do, it's not a problem!
