One of the rarer girls' names created in the late 19th century from vocabulary words for gemstones. This English word is ultimately derived (via Latin and Greek) from an Indian language (compare Sanskrit upala ‘precious stone’).
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.)
