I am searching the birth and parents of Marguerite Auten or Otten born 1741. She was married to Jean-Baptiste Colpron or Kaubraun or else..They settled in Quebec around 1785. They said to be Alsacians and spoke only german language at their arrival. They came with their young son George. I am searching their origin for more than 20 years. Any information will be greatly appreciated. Thanks a lot.
