The Au family name first began to be used in the German state of Bavaria. After the 12th century, hereditary surnames were adopted according to fairly general rules, and names that were derived from locations became particularly common. The family name Au is a local surname. Originally denoting the proprietorship of an estate or influence within a village, the German preposition von, which means from or of, used with local names, was taken as a mark of aristocracy. The surname Au was given to someone who lived in a wooded area, meadow, or pasture. The name stems from the German word Aue, which means woods or meadow. The name von der Aue gained widespread recognition from Hartmann von der Aue, who was a renowned poet of the 12th and 13th centuries. After the 13th century, the name Au became particularly popular in Bavaria, which was the primary location of seven noble families bearing this name. The Au family possessed vast estates and resided in an elegant feudal home in Bavaria. They also played an influential role in the social, economic and political development of the region.

Early Origins of the Au family

The surname Au was first found in Bavaria, where the Auer family name is considered to have made an early contribution to the feudal society which became the backbone of early development in Europe.

The name derives from the German word "Aue," which means meadow or pasture. Hartmann von der Aue ("of or from the meadow") was a renowned poet of the 12th and 13th centuries, and the name von der Aue gained widespread designation for those living in a wooded or pastured area. The name was particularly popular in Bavaria, which was the primary location of seven noble families bearing this name, dating back to the 13th century.

United States Au migration to the United States +

The great European flow of migration to North America, which began in the middle of the 17th century and continued into the 20th century, was particularly attractive to those from Bavaria who wished to escape either poverty or religious persecution. For many Bavarian tenant farmers, the chance to own their own land was a major incentive. So the widespread colonization of the United States began in 1650, when many immigrants from Germany settled in pockets in Pennsylvania, Texas, New York, Illinois, and California. In Canada, German settlement centered in Ontario and the prairie provinces. Among those of this surname listed in various historical records were:
