From an Old Norse female personal name composed of the name of the fertility god Ing + fríðr ‘fair, beautiful’. It was introduced into the English-speaking world from Scandinavia in the 20th century and became very popular, largely because of the fame of the Swedish film actress Ingrid Bergman (1915–82).
English and Scottish: patronymic from the personal name John. As an American family name, Johnson has absorbed patronymics and many other derivatives of this name in continental European languages. (For forms, see Hanks and Hodges 1988.)
