Any info on August Voisin & his wife Caroline Schaefer (1844 Ontario - 1889 Mecosta, Michigan) and their children: Theophilus b. 1869; Maria Anna Louisa b. 1871; Jerome August b. 1873; Carl Victor b. 1874; Rose b. 1876; Isabella Clara b. 1879. They all moved to Michigan in 1879 and I can't find any info on them after that.
