Last Name Ernoult

What is the origin of the last name Ernoult?

The surname Ernoult is of French origin, specifically from the region of Normandy. It is derived from various place names that share similar spellings, with the most likely being Ernoult, a commune in the department of Eure-et-Loir in north-central France. The name Ernoult itself comes from Old Norse personal names such as Arni (meaning eagle) and Oddr (meaning fortune or fate), which were introduced during the Viking invasions of France in the late 9th and early 10th centuries. The Norman conquest of England in 1066 brought these surnames to England, where they have remained in use ever since. In genealogy research, it is important to note that the spelling of surnames can vary greatly over time due to factors such as recording errors and regional dialects, making it difficult to definitively trace all instances of the name back to their original place of origin. However, the French village of Ernoult remains a strong candidate for the source of the surname.

Over time, residents of these places began to adopt these names as their own, thus creating surnames like Ernoult.
