Are you by any chance reading "The curious tale of the dog in the nighttime?" as Shiobhan is the main character in it.

[Tobus]

Thanks! That's not really what I was thinking it sounded like, so I'm glad I asked.

That is my daughters middle name. It means "God is gracious" The English is Joan.
It’s pronounced “shiv-awn”, like Chevonne, but with more of an “ive” sound.

It can be heard HERE

I figured someone had been watching American Idol with that really pretty girl named Siobhan who got cut a couple weeks back.

My wife had asked me how to pronounce her name, but I hadn't seen the show until then. She was as pretty as her name, and I had to give a short lesson in Gaelic pronunciation which my wife was uninterested in!

There's a fiery lass at my office with the name, and she pronounces it as wvpiper suggests.
