Origin of a name

Surnames started to appear durind the middle ages. At the beginning, they were given mostly to royalty and noblemen. During the 13th century, with the problem of having more and more individuals with the same first name , surnames started to spread.

The Comeau surname is considered topographic. These names were mainly given to individuals in regard to their location. So, the surname Comeau would have been given to an individual livling in a combe, a valley.

In the Recueil des actes des comtes de Pontieu (1026-1279), Paris : Imprimerie nationale, 1930 from Clovis Félix Brünel (1884-1971), we witness the first mention of the name, november 5th, 1101. A quarrel presided by Robert de Bellême, between the abbot Arnoul de Saint-Martin de Troarn and the knight Robert Samson. The origin of the quarrel between the two man was the ownership of the Commeaux land. A second document mentions the surname in 1276, confirming the ownership of the Commeaux land to the Troarn abbey. Commeaux was written in latin as Comels.

So the origin of the surname would have appeared in this region.  A Lower Normandy commune in France still is named Commeaux:

The first time we encounter an individual with the Comeau surname is in 1348, in another french commune, Poully-en-Auxois, in Burgundy:

Wikipedia – Pouilly-en-Auxois

On a tombstone it is written:


or “Here lies Herbert Comaul who died in the year 1348″

It is believed that this Herbert Comaul could be the ancestor of Guyot de Comaul or Guy de Commeau (c. 1495), the known ancestor of the De Comeau genealogy in this region, made of noblemen, military and lords.
