Mollipops, Cai is pronounced Kye to rhyme with tie as C in Welsh is hard, Ieuan is Y (as in yacht)-eye-un.
Have to say that boys can be harder in Welsh, how about Dafydd, Ioan, Rhodri, Llyr,Owain, Euros? There's a brilliant book called Welsh names for your baby by Meic Jones which has loads of great names, it has a pronunciation guide in it.Have to say that I don't like Rhys at all, partly because the Rh sound is slightly different in Welsh and I don't think all anglo-saxon ears/tongues pick it up so the name doesn't sound right and also because of a particularly difficult child I work with called that!
Does anyone else find that they are really influenced by people they meet/know who have certain names? I'm always really on edge with anyone called Amy because the 1st girl I knew with that name (aged 6y) was a spiteful little madam. A nursery teacher friend had real problems naming her DS as she had encountered so many horrible little boys!
