This interesting surname derives from a Norman personal name Herluin or Arluin, composed of the Germanic elements "erl" meaning warrior, plus "wine", friend. This personal name introduced into England after the Norman Conquest of 1066 appears as "Herluinus", and "Hrleuuine" in the Domesday Book of 1086, and as Herelewine de Sumerfeld in the Pipe Rolls of Kent in 1191. The surname dates back to the early 13th Century (see below). Further recordings include Roger Herlewyn (1230) in the Pipe Rolls of Dorset, and Alice Hurlewyne (1332) in the Subsidy Rolls of Surrey. In the modern idiom, the surname has many variant spellings ranging from Hurlin, Harling and Arling to Urlin and Urlwin. London Church Records show the marriage of Edward Hurling to Jane Bistock on February 7th 1716 at St. Dunstan's, Stepney. Thomas, son of Thomas and Sarah Hurlin, was christened on February 11th 1689 at St. Giles, Cripplegate, and Elizabeth, daughter of John and Rebecca Hurling, was christened on May 19th 1723 at St. Mary Whitechapel, Stepney. The first recorded spelling of the family name is shown to be that of John Erlewin, which was dated 1225, in the "Calendar of Patent Rolls of Kent", during the reign of King Henry 111, known as the Frenchman, 1216-1272. 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.
