Russian-German Settlers in Africa

I just found out that a number of Russian-Germans settled in German East Africa (today Tanzania) during 1906-1907 as part of an Imperial German government program to settle Europeans in the colony. By 1908 there were 67 Russian-German families in the colony out of a total European population of 2845 people (pp. 577-578). I was unaware that there had been any substantial settlement of Russian-Germans anywhere in Africa.
