scooby, why would it be a wind up, completely normal name and would go really well with surname!
It seems to come from an Irish name which is the disciple of some saint, or with an "i" is a hebrew name. Doesn't mean "discontented" as far as I can see. DH's family all from Ireland originally, though we are not Irish at all.
Not keen on it being shortened though as our surname is one syllable, which makes choosing names tricky (not to mention the fact that it is also a noun, so have to be really careful!).
I do really like it.
