The history of the last name Casselman

The surname Casselman is of Germanic origin, with roots tracing back to the Middle Ages. The name is believed to have originated in the Rhineland region of modern-day Germany and the Netherlands during the 12th or 13th century.

One of the earliest recorded instances of the name appears in the Codex Diplomaticus Fuldensis, a collection of historical documents from the Fulda Abbey in Germany, dated around 1200 AD. The name is spelled as "Casselmann," which suggests a connection to the German word "Kassel," referring to a town or village.

Another theory suggests that the name may have derived from the Old German word "cassel," meaning "a small castle or fortified dwelling." This could indicate that the original bearers of the name lived near or were associated with such a structure.

As the name spread throughout Europe, it underwent various spelling variations, including Casselmann, Casselman, Kasselman, and Kaßelmann. The modern spelling of "Casselman" appears to have emerged in the 16th or 17th century.

One of the earliest recorded individuals with the name was Johannes Casselman, a merchant from the city of Cologne, Germany, who lived in the late 15th century. Another notable figure was Hendrick Casselman, a Dutch explorer and navigator who participated in several expeditions to the Americas in the early 17th century.

In the 18th century, a branch of the Casselman family migrated to the American colonies, where they settled in Pennsylvania and Maryland. One prominent member was Jacob Casselman (1737-1809), a farmer and landowner who served as a captain in the Continental Army during the American Revolutionary War.

Other notable individuals with the Casselman surname include:

1. John Casselman (1812-1884), a Canadian politician and businessman from Ontario.
2. William Casselman (1866-1935), an American businessman and philanthropist from Pittsburgh, Pennsylvania.
3. Heinrich Casselman (1874-1943), a German-American artist and illustrator known for his paintings of the American West.
4. Frédéric Casselman (1909-1985), a Belgian mathematician and academic who made significant contributions to the field of algebraic geometry.
5. William Casselman (born 1942), an American mathematician and professor emeritus at the University of British Columbia, known for his work in representation theory and automorphic forms.
