The First Wellington
The earliest reference to the surname in genealogy website records is Peter Wellington, born in 1563 in Torrington, Devon, England.
Origin of the Word Wellington
The origin of Wellington is most likely from the town of Wellington in Somerset, England. It was originally known as Weolingtun in the Anglo-Saxon period and was recorded by the name of "Walintone" in the Domesday Book of 1086.
Old English 'Weolingtun'
Earlier it was recorded that Edward the Elder gave land known as Weolingtun to Bishop Asser in exchange for the monastery of Plympton in Devon. Weolingtun meant "Wealthy Estate" in Old English and may have been used as a first name for a short period of time.
According to the Oxford Dictionary of Place Names, the name Wellington has a possible origin with an estate of a person called Weola (meaning "wealth" in Anglo-Saxon) in very early times. Our word for "will" has its origins in this word.
