Is anyone aware of online lists of cantonists and their schools and their subsequent military service? I am looking for information about Yitzchak Friedman who was taken in 1852 from Khotin, Bessarabia at the age of 8 or 9. If he served 25 years after turning 18, he would have been discharged about 1886. However, his children were born in the 1870s. He may have been a colonel at time of discharge near Rannenberg/Oranienberg/Chaplygin in Lipetsk Oblast south of Moscow. After discharge he served in the Rannenberg Police Force. He married and had children in the area between Rannenburg and Moscow, but I have no documents. He emigrated in 1907 to join children who had settled in South Bend, Indiana. FYI, as an adult he only remembered the given name of his father, not where he was born. It was only through a DNA match with other Friedmans and corroborating information from Revision Lists that the family determined more about his roots.
Any information on list of schools and their students or military lists from about 1860 onwards would be appreciated.
