Through my research I believe that Jean Aveline di St. Jule and Catharine Guilbalt are my g-g-g-g-g grandparents through their child Jacques and his son Francois, who kept the Aveline name. This branch of the family migrated to Indiana through Detroit and were involved in the fur trade. The problem is that I have had difficulty soucing this line from Jean to Jacques to Francois. Have you found anything? Also, I do not have anything about either Jean or Catherines parents.
