The name Harry originally stems from the Old German 'Heimirich', meaning 'Home ruler'.
Harry is technically a diminutive of Henry, but using it as a de facto first name is not a modern phenomenon. Most of the English King Henrys were referred to in their time as Harry – most notably Henry V in Shakespeare's famous rallying cry: "God for Harry, England and St George!"

Surnames to avoid Harry with:
Surnames beginning with an 'I' sound, ie. Inman or Ingman, might cause problems as when said aloud this combination of sounds may result in elision – when two words are slurred together end up sounding like one. Families named Henderson should probably also give Harry a miss, lest their offspring be confused with the hairy star of Harry and the Hendersons.
Foreign variants include Enrique (Spanish), Enrico (Italian), Henk (Dutch), and Henning (Scandinavian) as well as the Scottish version, Hendry.
Similar English names include Henry, Harold, Harrison, Harvey and Hugo.
English variations include: Henrietta, Harriet, Hattie, Hettie, Etta, Hallie, Halle
