Broadway Family History

English:: habitational name from either of two places called Broadway in Worcestershire and Somerset named in Old English with brād ‘broad’ + weg ‘way road’ or a topographic name with the same meaning. See also Bradway.

Possibly a habitational name from Broadwey in Dorset ‘the broad manor on the Wey river’ named with Old English brād ‘broad’ prefixed to Wey an ancient pre-English river name.

But it is unlikely to be the source of the modern surname.
