Hmmm it's one of those standard celebrity names that are uncommon among the general population but loved by celebs just like Tallulah and Blue as a middle name. Not very creative but it's okay. It makes me think of Fawkes the Phoenix from the Harry Potter books so it's a word that doesn't really work that well as a name for me but it's not horrible or anything and goes nicely with Robert which is also fine but nothing special. Camden John and Brooklyn Elisabeth are similar in style so they go nicely together but they are all kind of bland. Very bland actually.
