Too popular?

My great grandmother recently passed away, and it made me realize how much I really want our baby boy to have a family name that holds a lot of meaning. I've never cared for it before now, but I'm suddenly over the moon for the name Ollie -- my great grandfather's name. I know the name Oliver is SO popular, and most mommas will be calling their baby Ollie. I wanted a unique name, and this would be the opposite, but should I go with it anyways since it has meaning?
