Sebastian Leikam (age 18) and his brothers Anton (age 16) & Andreas (age 13) settled in the Volga German colony of Ober-Monjou on 17 August 1767. They are recorded there on the 1767 census in Household No. 35 along with their stepfather, Christoph Vogel. [The translation of the 1767 census by Igor Plehve erroneously records this surname as Lenkof.]
In 1780, Andreas Leikam moved from Ober-Monjou to Katharinenstadt.
