The surname Wheelock is of English origin, deriving from an old place name, and dates back to the medieval period. The name is a compound word, combining the Old English terms "hweol" meaning wheel and "ac" meaning oak tree, indicating an oak tree situated by a wheel or mill-wheel.
Records show that the name was first found in Worcestershire, where the family held estates and lands after the Norman Conquest of 1066. One of the earliest recorded bearers of the name was William de Whelok, who was mentioned in the Pipe Rolls of Worcestershire in 1221.
During the Middle Ages, the Wheelock family played a significant role in the region, and their name appeared in various historical documents. In the Domesday Book of 1086, a reference is made to a place called "Wheluche" in Worcestershire, which is believed to be the original location associated with the surname.
In the 14th century, the name Wheelock was also found in Lancashire, where John de Whelok was listed in the Wills at Chester in 1362. This suggests that branches of the family had spread to different parts of England by that time.
One notable bearer of the name was Ralph Wheelock (c. 1600-1683), an English Puritan minister who emigrated to Massachusetts Bay Colony in 1637 and became one of the founders of the town of Medfield.
Another prominent individual was Eleazar Wheelock (1711-1779), a Congregational minister and educator from Connecticut, who founded Dartmouth College in 1769, one of the oldest institutions of higher education in the United States.
