What is the pronunciation of these Welsh names?

I just finished reading Bernard Cornwell's "The Warlord Chronicles" and was wondering how to say the Welsh names. I found some on his website, but the two that I wondered about the most are "Seren" and "Gwydre".

Thanks for your help!

Traditional Welsh Music in English Language?

Hi there. I'm looking for traditional Welsh music CDs, but in the English language, since I can't understand Welsh, of course! Anyone have any suggestions of where to look?
Thanks for your help.
