I love them both. The meaning for
Rhiannon is wonderful...I think for me, using one or the other would depend on the middle name chosen.
Sadly, although this is one of my top girls names, I will never be able to use it. One of my cousins beat me to the punch. And spelled it
Reanna. Which is ok, I guess, but not nearly as nice as
Rhianna or
Rhiannon.
