I really don't have alot of information except that Rene Durocher came from France and apparently he went to New Orleans. According to a letter that my Aunt had his brothers sent him to New Orleans from France. His Parents names were Joseph Durocher and Marguerite LeRoy. They were from Anjou, France. Rene and two older brothers that went to Montreal Canada. The brothers came from France about 1741so I think it would be after that. I think Rene was a younger brother. So different spelling are DeRocher, delaroche, Laroche, Roche, Rocher. That is about all really know. I had a counsin that lived in New Orleans and he said that he saw street that were names from someone named Durocher.
