The history of the last name Iller

The surname ILLER is believed to have originated in Germany, with its roots tracing back to the Middle Ages. It is thought to be derived from the German word "Iller," which is the name of a river that flows through the southern regions of Bavaria and Baden-Württemberg.

The earliest recorded instances of the surname ILLER can be found in historical documents from the 14th and 15th centuries, particularly in areas around the Iller River basin. One notable mention is in the chronicles of the city of Ulm, where a family with the surname ILLER is referenced in the year 1417.

During the 16th and 17th centuries, the name ILLER began to spread beyond its original geographic boundaries, appearing in records from various parts of Germany and neighboring regions. This dispersion was likely due to migration and the expansion of trade routes.

One of the earliest known individuals with the surname ILLER was Hans Iller, a merchant from Augsburg, who was born in 1532 and died in 1602. He is mentioned in several historical documents related to trade activities in the region.

In the 18th century, the name ILLER gained further prominence with the birth of Johann Iller (1711-1784), a German theologian and philosopher who made significant contributions to the field of ethics and moral philosophy.

During the 19th century, the ILLER surname was carried by notable figures such as Friedrich Iller (1818-1892), a German painter and artist known for his landscape and genre works, and Heinrich Iller (1849-1921), a German politician and member of the Reichstag (the imperial parliament).

Another individual of note was Theodor Iller (1872-1954), a German architect who designed several prominent buildings in cities such as Munich and Berlin. His works are considered examples of the Art Nouveau and Jugendstil architectural styles.

The ILLER surname has also been associated with various place names and locations throughout Germany, such as Illertissen, a town in Bavaria located along the banks of the Iller River, and Illerzell, a municipality in the district of Alb-Donau in Baden-Württemberg.

While the ILLER surname may have evolved and spread across different regions over the centuries, its roots can be traced back to the Germanic regions along the Iller River, where it originated as a locational surname reflecting the geographic ties of its earliest bearers.
