Ffion

The 2 Fs sound just like 1 F. It's simply pronounced FEE-on ('on' as in the word on). It's simple to pronounce. It's not ef-fee-on like someone else said.

I'm Welsh and know loads of Ffions (it's a very popular name here) so trust me, I'm correct.

Hi, my names Ffion and my name's pronounced Fee-on, not f-fee-on, but it's funny when people do, and it's also not pronounced ef-ee-on. Hoped I helped people.

It's pronounced "Fee-yon".

Pronounced Phee-on (the "ph" is how you pronounce "ff" in Welsh).

I've only heard this pronounced as fee-ON.

It's pronounced EFf-ee-on. Effion. Therefore Ffion. William Hague's (ex-Tory leader, UK) wife bears this name and he pronounced it 'EFfion'.
