My last name is Blanchette and it is a french last name. My great grandfather was born in Canada and came to America when he was young. I know that at some time in the late 1700's my ancestors moved to Canada from France. There are not many other Blanchette's in the area other than my relatives. I was not able to find any information on this site but from my own research I have found out that it means, "Without satin".
