For those of you with a want to come to a small church, in the rolling hills of West Wales, Annie and I plan to have a small blessing at my family church in Hebron, exact dates are not nailed down yet.

How do I say his darn name?

Here's a few links I found using that google machine....

Dafydd — Pronunciation: Dahvith (This “th” is like the “th” in “this.”)

Even though Welsh and English use almost the same Roman letters, the letters don't always represent the same sounds. For example, 'dd' in Welsh stands for the same sound as 'th' in English 'the', and Welsh 'f' conveys the sound which English usually represents with 'v'. Not knowing this has lead many an English speaker to pronounce Dafydd 'David' as though it were 'Daffid' rather than 'Davith'.

An audio file with a full welsh name (Dafydd Ap Gwylim)... careful, the recording is pretty fast.
