Osman or Usman is the Turkish, Persian, and Urdu transliteration of the Arabic masculine given name Uthman.
In England, however, Osman is an English surname whose history dates back to the wave of migration that followed the Norman conquest of England in 1066, though it is pronounced with a long "o".
The name Osmar and Osmer (without surname) appears in the Domesday Book of 1086 for Leicestershire and Devonshire, respectively, but the surname did not appear until the early part of the 13th century.
In April 1635, clothier James Hosmer, his wife Ann and two daughters, Marie and Ann, embarked from London on the Elizabeth bound for New England.
The first recorded spelling of the family name is shown to be that of William Osmere, which was dated 1230, in the Pipe rolls of Devonshire, during the reign of King Henry III.
