The Native Sons of the Old Sixth Ward (NSOSW) was founded in 1942 by Robert Uihlein,
Sr. and Fred Nieser. It was a social club for people born in the Sixth Ward of
Milwaukee, Wisconsin, before 1900. The requirement was later changed to 1910. The
old sixth ward was roughly the area north of Vliet Street and between the Milwaukee
River and Seventh Street, now Schlitz Park. They met annually, often times at the
Schlitz Brown Bottle. The group is no longer extant.
