I like Barnaby. It gives off a quintessential British gentleman vibe. It sounds cute but it's a name of substance and a long history. I can see Barnaby with siblings named Crispin, Ivor, Peregrine, Nigel, Lysander, Rufus or Rupert. His sisters would be called Agatha, Araminta, Clementine, Annabel, Cordelia, Millicent or Winifred.
