This very ancient and interesting surname is of Anglo-Saxon origin, and is a locational name from Yewdale in Lancashire, so called from the Olde English pre 7th Century "iw", yew tree, and the Middle English (1200 -1500) "dale", from the Olde English "dael", valley, and means "yew valley" or "valley of yew trees". The placename was first recorded as "Ywedalebec" in the Feet of Fines of 1196. Locational surname were developed when former inhabitants of a place moved to another area, usually to seek work, and were best identified by the name of their birthplace. Recorded in the Church Registers are the wedding of Maudline Udale to one Wyllyam Smyth at St Andrews Church, Enfield, Middlesex on October 6th 1600, and the christening of Thomas, son of Thomas Udall, on September 25th 1664 at Clitheroe, Lancashire. Another recording is that of the marriage of James Udall and Elizabeth Kilner on June 8th 1680 at Cartmel Priory Church, whilst somewhat later on June 10th 1832, Joseph Udale married Anne Connell, at St James, Paddington. The Coat of Arms most associated with this name is very old; it is silver, a cross moline red. The modern surname can be found as Udall, Udale, Udell, Yewdale, Yoodall, Yedall and Uvedale. The first recorded spelling of the family name is shown to be that of Alicia de Yowdall, which was dated 1379, in the "Yorkshire Poll Tax Returns", during the reign of King Richard 11, known as "Richard of Bordeaux", 1377 - 1399. 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.
