The date is pre 7th Century and it is possible that a place called 'Noseworthy' existed, but if so, the location now appears to be lost, or the spelling is corrupted from Northey. The dweller at the North Farm, the Noseworthy, all the original recordings were from Wiltshire, where the normal ending of "worth" is often transposed to "worthy" - although the meaning remains the same. In 1730, One Joseph Nosworthy, a Carpenter, married Elizabeth Pomfett, at St. Georges Church, Hanover Square, London. The first recorded spelling of the family name is shown to be that of Walter Noswuth. which was dated 1273, The Pipe Rolls of Wiltshire. 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.
