The birthdate for Louis GUERIN dit ST-JEAN, son of Jean-Baptiste, agriculteur & Louis Dupol is 1804-12-02 and baptism is 1804-12-03. St Leon-le-Grande, Maskinonge, Quebec. Godparents are Dupol Louis & Belanger Marie. For Louise Drolet, I do not have a date, but the 1851 census in St-Paulin, Quebec reports her birthplace as Ancienne Lorette and age is 44. The 1860 census in St. Anne, Kankakee county, Illinois, USA lists her age as 53. That places a birth year of about 1807 at probably Ancienne Lorette. I beleive that I may have found another marriage for Louise (Drolet) ST-JEAN in 1866. I am still looking for more confirmation and a death of Louis GUERIN dit ST-JEAN between 1860 and 1866.
