Guess what, DP and I have a bunch of relatives called John. DP's mn is John and he has never liked it - it's so boring. For sentimental reasons I'd love to include some variant in our child's name if we have a boy, but God it's a struggle to come up with any that we like besides Ivo, which I think is maybe not an obvious link to English ears.
My cousin has already named her child one of the (v nice) Welsh forms of John, so maybe she's paid the family dues.
