Oh help, help, help heeeeelp!! (As I seem to have said when attempting to name the previous child!!)

Bubba number 3's gender will remain a mystery so we need both and can agree on very, very little. I'd like a name that 'fits' with our other two and unfortunately a couple of the names I love are rhymy or clash with our surname.

Kiddles are I.vy and O.wen
Surname is C.....ham - think Happy Days!

Looking for something unusual (nothing in top 30 of BDM names) but not super 'out there'. DH is anti-any names that might be considered a surname (such as Harvey, Jackson....)


Any inspirations on great names, boy or girl, that go well with our other two?
