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).
Olivia has been used in the English-speaking world since the 18th century, though it did not become overly popular until the last half of the 20th century. Its rise in popularity in the 1970s may have been inspired by a character on the television series The Waltons (1972-1982) [2] or the singer Olivia Newton-John (1948-2022). In 1989 it was borne by a young character on The Cosby Show, which likely accelerated its growth. It reached the top rank in England and Wales by 2008 and in the United States by 2019.
A famous bearer was the British-American actress Olivia de Havilland (1916-2020).
