fact sources and writings about this individual:
Swiss passport to the US through France, 1854. 
1880 Census, Gratiot County, St. Louis. Lists Jacob(55), Susanah(39), and Gustavus(18). 

Gladwin County Record (newspaper) 19 and 26 Nov 1880--account of the accidental shooting and subsequent death of Jacob. Certificate of death lists (incorrectly) village of Gladwin, county of Gratiot as death place. He lived in Gratiot County, but died in Gladwin County... 
Buried in St. Louis cemetery. 

Big mystery: apparently his wife, Susanah died in or before 1869, leaving real estate to her son Gustavus/Augustus (age 8)[why??]. A year later, Jacob deeded the property away along with his (new?) wife Susannah! Have found no record of their marriage or of the first's death other than in the probate record establishing Jacob as Gustavus's guardian so Jacob could dispose of the real estate... Jacob was a practicing physician (in St. Louis?)
