It would be pronounced Ree-in. (Not Ryan). Thoughts?
I’d spell it [name_u]Rhian[/name_u] 
But it is a strong, sweet name
Spelled Rhian, this is one of my favourite names ever! So sweet and distinct.
i’d also spell it [name_u]Rhian[/name_u], a lovely strong name
[name_u]Love[/name_u] it! But I also prefer [name_u]Rhian[/name_u]!
