Pierre Sylvestre Chouteau (may have went by the name of Sylvestre Chouteau) married Louise Alvarez on Aug 4 1846. Did they marry in St. Louis? Did they divorce? He died in 1886, but is not on 1880 census. Louise was on 1880 census, but living in Edouard St-Michel's home. Does anyone know anything of Mrs. Chouteau or her side of the family?
