RAINEY Family History
Recorded in many forms including Rainy, Rainey, Rany, Raynie, Reany, Reaney, Rennie, Renny, Rennison, and Renison, this is a surname of complicated and confusing origins. It can be English, Anglo-Irish, Irish, Anglo-Scottish or Scottish, and with overlapping spelling. In most cases it is, or rather was, a form of the original personal name "Reynold". This was of Germanic origin from the elements "ragin" meaning "counsel", and "wald", rule. Introduced into the British Isles by the Norse-Vikings of the 8th century, and later reinforced at the time of the Norman Conquest in 1066 by the French equivalent "Reinald", it rapidly gained popularity in the medieval period.
