The given name Chesney has its origins in the Old French language, emerging during the Middle Ages. It is derived from the word "cheisne," which means "oak tree" or "oak wood." This name was likely given to individuals who lived near or worked with oak trees, or perhaps even born under an oak tree.

During the medieval period, the name Chesney was commonly found in regions of France, particularly in the northern and central areas. As the name spread across Europe, it evolved into various spellings such as Chesneye, Chesnaye, and Chesnay.

One of the earliest recorded instances of the name Chesney can be traced back to the 12th century. In the Cartulary of Savigny, a medieval manuscript from France, a person named Chesney de Bray is mentioned as a witness to a land transaction in the year 1162.

Throughout history, several notable individuals have borne the name Chesney. One of the earliest was Sir John Chesney, an English military engineer and explorer who lived from 1793 to 1885. He was known for his surveys and explorations in the Middle East, including the regions of modern-day Syria and Iraq.

Another prominent figure was Charles Cornwallis Chesney, an English writer and explorer who lived from 1826 to 1876. He is best known for his expedition to explore the Euphrates and Tigris rivers, as well as his literary works documenting his travels in the Middle East.
