Oh please no. I think full names with more than regular noun in there sound daft, mostly like paint colours or something an advertising agency would dream up. I think you can only get away with one regular noun in First, Middle, Surname. I'm assuming Grace is a middle name here rather than a surname? It makes the first name sound like an adjective and really doesn't work I'm afraid. I guess you probably think the same yourself or you wouldn't have posted...
