If you're Irish, there is a good chance that you'll have curly strands of hair on your head. It might be full on curly-wurly or there might just be the odd one or two sticking out making styling your hair a nightmare from the day you begin.
Wayne and Coleen Rooney announced the birth of their fourth baby in February and they decided to break their tradition of names beginning with K - Kai, Klay and Kit.
Their fourth child will be called Cass Mac Rooney and while many believe that it could be short for Cassius, there is actually a lovely Irish meaning behind the name.
According to She Knows baby names, although Cass means 'wealthy man' in English and 'vein' in Latin, in Irish, it means 'curly-headed'.
So in a rough translation, Cass Mac Rooney means curly-headed son of the Rooneys.
It's kind of a sweet name when you think about it but if he doesn't live up to his curly-headed expectations, we'll be kind of disappointed.
Know anyone who should have been called Cass? Let them know in the comments.
