The history of the last name DeLong

The surname DELONG has its origins in France, dating back to the 12th century. It is derived from the Old French phrase "de long," which means "from long" or "from far away." This suggests that the name was initially given as a descriptive nickname to someone who had traveled a great distance.

The earliest recorded instances of the name can be found in medieval French records, such as the Cartulaire de l'Abbaye de Saint-Bertin, which mentions a "Radulfus de Long" in the year 1185. This document, a cartulary from the Abbey of Saint-Bertin in Saint-Omer, France, provides evidence of the name's existence during that time period.

In the 13th century, the name appears in various forms, including "de Longe," "de Longue," and "de Longa," reflecting the variations in spelling that were common in the Middle Ages. These variations likely stemmed from local dialects and regional pronunciations.

One notable bearer of the DELONG surname was Jean de Long, a French nobleman and military commander who fought in the Hundred Years' War. Born around 1320, he served under King John II of France and was present at the Battle of Poitiers in 1356, where he was captured by the English.

Another historical figure was Pierre DeLong, a French explorer and navigator who accompanied Jacques Cartier on his second voyage to Canada in 1535. DeLong played a crucial role in mapping the St. Lawrence River and establishing trade relations with the indigenous peoples.

In the 17th century, the name appeared in various parts of Europe, including the Netherlands, where it was sometimes spelled "de Longh." One prominent individual was Jan de Longh, a Dutch painter and engraver active in the mid-1600s, known for his landscapes and cityscapes.

The DELONG surname also found its way to the British Isles, where it was sometimes anglicized as "Delong" or "DeLong." One notable bearer was Thomas DeLong, an English mathematician and astronomer born in 1699, who made significant contributions to the study of comets and planetary motion.

In the 19th century, the name gained prominence in the United States, with several individuals bearing the DELONG surname making their mark. One such person was George W. DeLong, an American naval officer and explorer who led the ill-fated Jeannette expedition to the Arctic in 1879. Although the expedition ended in tragedy, DeLong's leadership and bravery were widely acclaimed.
