Origin
Meaning and origin of Landua
The surname Landua has its origins in Germany, dating back to the 16th century. It is believed to have derived from the Old German word "landau," which referred to a type of carriage or coach that was first manufactured in the town of Landau, located in the southwestern region of Germany.
The earliest recorded instances of the surname Landua can be traced back to the late 1500s, with mentions in various historical documents and town records from the German states. One notable example is found in the Palatinate census records of 1589, which lists a family by the name of Landua residing in the town of Neustadt an der Weinstraße.
In the 17th century, the name Landua appears in several military records, indicating that individuals bearing this surname served in various German armies and regiments during the tumultuous years of the Thirty Years' War (1618-1648). One such example is Johann Landua, a soldier who fought in the Imperial Army under the command of Count Tilly.
As the centuries progressed, the Landua surname spread across various regions of Germany and neighboring countries, with some variations in spelling, such as Landau, Landauer, and Landuer. In the 18th century, a notable figure was Friedrich Landua (1722-1798), a German philosopher and educator who served as the rector of the Gymnasium Illustre in Hanau.
Another significant individual was Carl Landua (1848-1924), a German jurist and legal scholar who made significant contributions to the field of criminal law. He was born in Berlin and served as a professor at the University of Würzburg and the University of Münster.
In the realm of literature, one cannot overlook the acclaimed German writer and poet, Ines Landua (1933-2020), whose works explored themes of love, identity, and the human condition. Her poetry collections, such as "Übergangszeiten" (Transitional Times) and "Lebensformen" (Forms of Life), garnered widespread acclaim and critical recognition.
Throughout its history, the surname Landua has remained predominantly concentrated in Germany, with smaller pockets of individuals bearing this name found in neighboring countries like Austria, Switzerland, and the Netherlands. While the name may have evolved slightly in spelling over time, its German roots and connection to the town of Landau remain firmly embedded in its etymology.

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.
