What do they call Santa in Wales?

In Wales, Santa is known as 'Siôn Corn', which is a translation of 'Father Christmas'. The Welsh word 'Siôn' is derived from the Latin 'Johannes', meaning 'John', while the word 'Corn' is derived from the Old English word 'corn', meaning 'grain'. The combination 'Siôn Corn' translates literally as 'John Grain', and is a reference to the festive tradition of giving gifts of food and drink at Christmas.
