Google's machine translation is a useful starting point for translations, but translators must revise errors as necessary and confirm that the translation is accurate, rather than simply copy-pasting machine-translated text into the English Wikipedia.
Do not translate text that appears unreliable or low-quality. If possible, verify the text with references provided in the foreign-language article.
In the Picard dialect, it is called Etré. The etymology of the name is from strata, after the stone-layered Roman roads in the area.
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.
