The word haggard originates from Old French (hagard), meaning "wild" or "untamed", originally describing a hawk caught as an adult for falconry, and became a technical term for a wild-caught, adult hawk (a "haggard hawk").  It later evolved to describe a worn, gaunt, or exhausted look.   As a surname, it can come from this French root, a Germanic word for "hedge" or "wood" implying something unenclosed or wild. (hag) or a nickname for a wild person or an occupational name for a falconer.  It could have even come from Danish (Viking) as an Americanized form of Danish names like Ågård (farm by a stream). or from Gaelic roots from Mac-an-t-sagairt, meaning "son of the priest".  Two famous individuals with the surname Haggard are: H. Rider Haggard, a famous 19th century author of adventure novels (e.g., "King Solomon's Mines"), and Merle Haggard, an influential American country music singer.
