When I was at university, deep in the previous millennium, I knew a Cleone (who was, sadly, quiet and inconspicuous); and at present there's a DJ on the national pop music radio station who's also a Cleone, though a very different one! So far these have been the only ones I've heard of; it sounds Greek to me, in more ways than one, but my student friend was of Afrikaans and English extraction and the DJ could be anything but her surname isn't audibly Greek at all.
