All double barrelled names are with a few earlier exceptions, the Victorian equivalent of the pre 8th Century Anglo Saxon personal compounds such as "Sieg-fried" or "Sea-Weard". This is to say, that they provided a conjoined identification but usually without a meaning. In this case the elements are formed from the pre 10th Century baptismal "Madoc", which translates as "The fortunate one". Madoc ap Cynan was the founder of the VIII, Royal Tribe of Wales circa 1040. The surname "Jones" is a patronymic of Hebrew origin and means "The Son of John". The first recording is in England, the association with Wales being circa 1500. The first recorded spelling of the family name is shown to be that of Matilda Jones, which was dated 1279, The Hundred Rolls of Huntingdon, during the reign of King Edward I, The Hammer of the Scots, 1272 - 1307. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.
