(male) Via Latin Gregorius from the post-classical Greek name Gregōrios ‘watchful’ (a derivative of gregōrein ‘to watch, be vigilant’). The name was a very popular one among the early Christians, who were mindful of the injunction ‘be sober, be vigilant’ (1 Peter 5:8). It was borne by a number of early saints. The most important, in honour of whom the name was often bestowed from medieval times onwards, were Gregory of Nazianzen (c.329–90), Gregory of Nyssa (d. c.395), Gregory of Tours (538–94), and Pope Gregory the Great (c.540–604). A famous bearer of the name in modern times is the film star Gregory Peck (1916–2003). The name has traditionally been popular in Scotland, where it is often found in the form Gregor.

FOREBEARS Johnson is the second most frequent surname in the U.S. It was brought independently to North America by many different bearers from the 17th and 18th centuries onward. Andrew Johnson (1808– 75), 17th president of the U.S., was born in Raleigh, NC, the younger son of Jacob Johnson and Mary (or Polly) McDonough.Little is known of his ancestors. The 36th president, Lyndon B. Johnson, dates his American forebears back seven generations to James Johnston (sic) (b. about 1662) who lived at Currowaugh, Nansemond, and Isle of Wight Counties, VA. Noted early bearers also include Marmaduke (d. 1674), a printer who came from England to MA in 1660; Edward (1598–1672), a colonial chronicler who was baptized at St.George's parish, Canterbury, England, and emigrated to Boston in 1630; and Sir Nathaniel (c. 1645–1713), a colonial governor of Carolina, who came from County Durham, England.
