In the early 1800s, one of the Kroeger clockmakers, Johann (1754–1823), followed the call of Catherine the Great, Empress of Russia, to settle in the Russian Empire (in regions that are now southeastern Ukraine). The Kroegers continued the clockmaking trade there and handed down their knowledge and craft through five generations into the early 20th century. Other families named Lepp, Hildebrand, Mandtler, and Hamm also made Mennonite clocks in the Russian Empire.
The Virtual Museum of Mennonite Clocks aims to collect information on these historic timepieces.
