Mervyn is a masculine given name and occasionally a surname which is of Old Welsh origin, with elements mer, probably meaning "marrow", and myn, meaning "eminent".[1]
Despite the misconception of the letter 'V' being an English spelling, through Roman occupation of Britain, the Welsh language (at least for spelling) was Latinised and through centuries of evolution of the Welsh language, the modern Welsh spelling for Mervyn is Merfyn.
