This interesting surname of English origin is a locational name from a place so called in Cumberland, deriving from the given name Lambin, itself a French short form of the German personal name Lambert, composed of the elements "land" meaning "land" or "terriroty" plus "berht" "bright" or "famous", plus "by" meaning "farm", hence, "Lambin's farm". The surname dates back to the late 16th Century, (see below). Variations in the idiom of the spelling include Lammonby, Lemonby, Lemmanbie, Lamanby, etc. George, son of Jo.
