The name Siobahn is a girl's name of Irish, Irish Gaelic origin meaning "God is gracious". Siobahn and is often added to lists like Soap Opera Baby Names and discussed in our forums with posts like "A brother or sister for little Jack or Olivia".
From the experts:
One of the most lovely -- and most confusing -- of Irish names , Siobhan (this and not Siobahn is the correct spelling) is sometimes rendered in a phonetic spelling such as Shevon or Shavonne. But while that clarifies things, it somehow undercuts the name's beauty, not to mention its authenticity.
