Johann Adam Schleibor, a farmer, and his wife Anna Katharina settled in the Volga German colony of Yagodnaya Polyana on 16 September 1767. They are recorded there on the 1767 census in Household No. 23 along with his stepchildren (Anna Maria Kroll, age 18; Johann Jakob Kroll, age 12; Johann Adam Kroll, age 10).
The 1767 census records that Johann Adam Schleibor came from the German village of Schwalmtal.
There are no known surviving male lines of this family among the Volga German colonies.
