This name of Anglo-Saxon origin is a topographical surname for a "dweller in the valley", deriving from the Old English pre 7th Century "denu", meaning "valley". Alternatively origin is from the Danish “Daner (Danes)”, from the Old Norse "Danir". Replaced native Old English "Dene". Both forms ultimately descend from Proto-Germanic "*daniz", meaning: A person from Denmark or of Danish descent, or a member of the Danes, a Germanic tribe inhabiting the Danish islands and parts of southern Sweden.
