It's pronounced ser-en like sarah. but with -en on the end not ah.lol
I prefer Cian spelling also Iriki as i'm welsh there's no K in the welsh alphabet so Cian would be a lot more suitable! Thnks for ur input. Seren Grace is my fav as Grace was the middle name of father's grandmother who passed away so thought "Grace's star" translated to Seren Grace would be lovely!
