The surname rhymes with 'Killer', so names ending in -er are out. I like names like Leo, Isaac, Hugo, Arlo, Kit, but have just realised (to my horror) that three syllable names like Alisdair have a much better ring!
Don't like Alisdair (it's a nice name, but I have a lisp). Can you suggest any others? (preferably without 's' sounds! Z is fine ..)
