Kellogg is an unusual and distinctive given name of American origin. It was initially used as a surname, derived from the Middle English word 'celoc', meaning 'fulling mill'. The name gained prominence in the United States during the 19th century, primarily due to its association with the famous brothers William Keith Kellogg and John Harvey Kellogg, who founded the Battle Creek Toasted Corn Flake Company in 1894. Today, Kellogg is considered a unique and non-traditional choice for parents looking for an uncommon name for their child. It is more often used as a surname but has gained some traction as a given name in recent years.
"Kellogg was indeed popular in 1927 with five babies bearing the name."
