I really like
Sinead,
Sian and
Sine.
The first time I saw
Siobhan I thought it was pronounced see-OB-(h)en.
When I found out it was pronounced shi-VAWN I was quite disappointed. I really dislike
Yvonne, and that is what the pronounciation reminds me of. I'd really like something with the same feeling as see-OB(H)-ahn and similar spelling.
Thanks for
Siomha, I really like that name.
