In the English-speaking world this name is more commonly given to girls. This is due to the American actress Alexis Smith (1921-1993), who began appearing in movies in the early 1940s. It got a boost in popularity in the 1980s from a character on the soap opera Dynasty.
Alto of Altomünster was an Irish or Scottish saint who lived in Germany.
Heinrich was popular among continental royalty, being the name of seven German kings, starting with the 10th-century Henry I the Fowler (the first of the Saxon kings), and four French kings. In France it was usually rendered Henri from the Latin form Henricus.
The Normans introduced the French form to England, and it was subsequently used by eight kings, ending with the infamous Henry VIII in the 16th century. During the later Middle Ages it was fairly popular, and was generally rendered as Harry or Herry in English pronunciation. Notable bearers include arctic naval explorer Henry Hudson (1570-1611), American-British novelist Henry James (1843-1916), American automobile manufacturer Henry Ford (1863-1947), and American actor Henry Fonda (1905-1982).
Due to the saint's renown, the name became common in the Christian world (in various spellings). As an English name, Luke has been in use since the 12th century alongside the Latin form Lucas. Both forms became popular throughout the English-speaking world towards the end of the 20th century. A famous fictional bearer was the hero Luke Skywalker from the Star Wars movies, beginning in 1977.
The name was not used in England until after the Protestant Reformation. A notable bearer was Martha Washington (1731-1802), the wife of the first American president George Washington. It is also borne by the media personality Martha Stewart (1941-).
It has occasionally been used as an English given name since the 16th century. It was moderately popular in the 1940s, but had a more notable upswing in the early 2000s. This may have been inspired by the Spanish actress Penélope Cruz (1974-), who gained prominence in English-language movies at that time. It was already rapidly rising when celebrities Kourtney Kardashian and Scott Disick gave it to their baby daughter in 2012.
