Care to share your thoughts on the girls name Siobhan (pronounced: shi-VAWN)?

I love the name now, but it took me forever to figure out how to say it and most outside of Ireland may not have a clue how to say it,either. so I think Siobhan is fine to use in Ireland, but otherwise, i'd spell it Shavonne, which is also Gaelic meaning "God is gracious". It's a form of Siobhan
