We were going to call dc2 Ezra (and referred to the bump as Ezzie for quite a while) but 'he' turned out to be dd. I have no intention of ever ever having another baby, but do sometimes think how nice it would have been to have had an Ezzie (although dd is obviously very delightful and I woudln't swop her for the world).
I think of it as mostly a chapel name because that's the context we first heard of it.
