The ancient and distinguished surname Cossart is originally of French origin, and refers to "a dealer in horses." The name was brought to England in the wake of the Norman Conquest of 1066, and became one of the many Anglo-Norman words that made up Middle English.

Early Origins of the Cossart family

The surname Cossart was first found in Essex, where the Cossart family was anciently seated as Lords of the Manor. For the three centuries following the Battle of Hastings in 1066, the language of the courts was French, and the Norman ambience prevailed. Norman surnames were held by members of aristocracy, and the Cossart family was a prominent one in the county of Essex. The family name was first referenced in the year 1299 when Ralph le Kossar held estates in that county.
