Origin
Meaning and origin of Isringhausen
The surname Isringhausen originated in Germany, likely in the late medieval period or around the 16th century. It is a locational surname, derived from a place name that may have been a small village or town. The name may have its roots in the Old German words "iser" meaning iron and "hausen" meaning house or settlement, suggesting it could have been a place known for iron production or ironworking.
One of the earliest recorded instances of the surname Isringhausen appears in the historical records of the city of Münster in Westphalia, Germany, dating back to the mid-16th century. These records mention an individual named Hans Isringhausen, who was a merchant and member of the city's guild.
In the 17th century, the Isringhausen name can be found in various church records and tax rolls from the regions of Westphalia and Lower Saxony in northern Germany. Some notable individuals bearing this surname during this time period include Johann Isringhausen, a Lutheran pastor born in 1635 in the town of Osnabrück, and Anna Maria Isringhausen, a landowner from the village of Rheinen, born in 1675.
During the 18th century, the Isringhausen family seemed to have spread across different parts of Germany, with records indicating their presence in cities like Münster, Osnabrück, and Bremen. One notable figure from this era was Carl Wilhelm Isringhausen, a merchant and ship owner from Bremen, who lived from 1720 to 1785.
In the 19th century, the Isringhausen surname continued to be found in various German states, with some individuals emigrating to other parts of Europe and even to the United States. One such individual was Friedrich Isringhausen, a German immigrant who settled in Pennsylvania in the 1840s and worked as a farmer.
Another noteworthy figure bearing the Isringhausen name was Theodor Isringhausen, a German entrepreneur and industrialist who lived from 1836 to 1905. He founded a successful textile manufacturing company in the city of Münster, which remained in operation for several decades.
While the Isringhausen surname is not among the most common in Germany, it has a long and documented history, with its roots likely tracing back to a small settlement or village in northern Germany during the medieval or early modern period. Its unique spelling and connection to the potential ironworking industry of its place of origin make it a distinctive surname with a rich historical background.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.

Keep in mind that these are self-reported numbers.
