In 1887 (Mannhardt, Jahrbuch, 67 f.) the Kronsweide congregation numbered 750 baptized members and 765 children. Meetinghouses then were found at Neu-Kronsweide and Schönwiese, and in all seven villages schools of good quality were being conducted.

In 1905 the Kronsweide Mennonite Church had a population of 1,925, of whom 900 were members. Unser Blatt reported in 1928 that the total population was 860 and the membership was 489. This apparently refers to the Kronsweide congregation and does not include the other Frisian branches. If it does, it would indicate that many of the members had immigrated to Canada. The same statistics reveal that the congregation had five ministers, four ministerial candidates, four deacons, in addition to the Elder Johann Martens. The majority of them had a secondary school training. Of the total congregation, 686 had Zentralschule education, 10 normal training, 52 secondary, and 3 university training.

Of the 80 families of Kronsweide who were taken to Germany by the German army in 1943, some 350 persons were sent back to Russia by the Russian army.
