The word "Ingalls" is a surname of English origin. It is derived from the Old Norse name "Ingialdr", meaning "son of Ing" or "descendant of Ing". "Ing" is a pre-Christian Germanic god associated with fertility, and the name Ingialdr would have referred to someone who was believed to be a descendant of this mythical god. Over time, "Ingialdr" evolved into different forms, including "Ingold" and "Ingalls". As a surname, "Ingalls" became more common in England, especially in the counties of Norfolk and Suffolk. It was later brought to America by English immigrants, including the Ingalls family famously known from Laura Ingalls Wilder's "Little House" series of books.
