'Hounslow' probably means the barrow, or mound, of the hound.
Old records spell it Hundeslow, from Anglo-Saxon hundes hlāw, the hound's barrow; whether the hound was a dog or a man named or nicknamed Hound is not known. The Domesday Book of 1086 calls the local hundred Hundeslaw. The station opened in 1909 as Hounslow Town and became Hounslow East in 1925.
