One commune is located in the canton of Catelet, Saint-Quentin arrondissement, département of Aisne, in the Picardy région.
In the Picard dialect, it is called Etré. Also known in ancient times as Strata or Estreti, history mentions an abbey in the 12th century. A parish was created there about 1189 with a priest sent from the abbey of Mont Saint Martin to buy land and help the poor. In 1777 Pierre Nicolas Leroy began manufacturing silk gauze here. Inhabitants are called Estrésiens.
The other commune is in the canton of Arleux, Duvai arrondissement, département of Nord, in the Nord-Pas-de-Calais région.
Other communes in the north of France also have "Estrées" as part of their names, e.g. Estrées-sur-Noye, Estrées-Deniécourt, Estrées-la-Campagne, Estrées-Mons, Estrées-Saint-Denis, Estrées-en-Chausée, Estrées-Lès-Crécy.
French nobility with the name Estrées originated in Artois. The line ended in 1771.
