Did you know there is a Maison Trestler in Vaudreuil? This house is now classified as a historical monument. They might have information in their archives. Just google "Maison Trestler" and you will find several references, some of them in English. Its own Web site is quite nice, and it says it will soon be translated in English. If there is a connection with this family, the site gives a lot of background on the original Trestler. Lorraine In Montreal
