The name "Aldridge" is derived from the Anglo-Saxon "alr" or "alre" + "wīc" meaning 'alder (tree) + village'. Another suggestion is that the name "Aldridge" means "outlying farm among alder-trees", from the Old English "alor" and "wīc". It was recorded as "Alrewic" in the Domesday Book of 1086 when it was valued at 15 shillings and had a population of seven households; the Lord was Robert (d'Oilly) and the tenant-in-chief was William son of Ansculf. The name was recorded as "Alrewich" and "Allerwych" in the 12th century.
