This surname is a local one meaning “the Welsh”, or someone who came from Wales. In his book, A Dictionary of English and Welsh Surnames, Charles Wareing Bardsley, he groups Wallace, Wallis, Walsh, Welch, and Welsh as the same group of surnames. It is a popular name among people of Scottish ancestry. In his book, An Etymological Dictionary of Family and Christian Names,Willia Arthur wrote “The same as Wales or Welch, and formed thus Gaulish, Wallish, Wallis, and also Welsh or Welch, a name given to the Britons by their Danish and Angles invaders, because they originally came from Gaul”. One author notes the surname comes from the Germanic cognate of Old English wealh, meaning foreign. The name derives from Strathclyde-Briton ancestry.
Sir William Wallace (d. 1305)
In his book, Homes of Family Names, H.B. Guppy states the following regarding this surname: “Wallace is a Scottish name established in the Lowlands, which has found its way into the north of England, but it must not be confused, when we are considering the migration of names, with the English Wallis found over the greater part of England, and established even in the extreme south-east and in the extreme southwest counties. It must, however, be noticed that though the Scotch Wallace and the English Wallis are distinct geographical variations, they are both of them forms of an ancient name in England. Le Waleis and Le Waleys were common names in the 13th century in the south and east of England, occurring especially in Wilts, Cambridgeshire, Oxfordshire, and Norfolk the first two of which WalKs is now a characteristic name. We also learn from the Hundred Rolls that De Walles was a Shropshire name in the 13th century. The original name was applied to a native of Wales.”
Another author states the surname has a distinct origin that is different from that of Walleys and Wallis in England and claims it derived from a very old personal name: Galgacus, a Caledonian chief, was identified by Baxter with Gwallog, a British name.
Early people recorded as bearing this surname include Henry le Waleis (Wiltshire), Roger le Waleis (Oxford), Adam le Waleys (Oxford), Iggelram le Waleys (Wiltshire), andWiliam le Wales (Sussex), who were recorded in the Hundred Rolls of 1273 AD. Howell le Walsshe and Mabil le Walleys were in the Placitorum in Dom. Cap. Westminster. John le Waleis and Ingleram le Waleys were found in Calendarium Inquisitionum Post Mortem. Richard Walays, Roger Walsche, William Wallays, and Alicia Walas were also recorded in the Poll Tax of Yorkshire in 1379 AD.
Another author notes the foreign equivalents are Valir (Norse) and Valas or Wealas (Anglo-Saxon), which mean foreigners or strangers. The Flemish is Wallays, which was a place name. There was a surge of Anglo-Normans into Scotland during the reign of King David I. Among these was Richard Waleys, the ancestor of the great William Wallace. He has left his name at Richardtun in Ayrshire. Valers is listed in the Roll of Battell Abbey,and de Vals, de Wals, Walo, Walise, Walscin, are all present in the Domesday Book. The north western part of France was called by the Norsemen, Walland.
