There were actually three Zimmerman-Willems marriages in my family:
1) my great-grandparents, Heinrich H. Zimmerman & Elisabeth Boldt Willems Zimmerman;
2) my grandparents, Jacob and Lena (Helena) Zimmermann Willems;
3) my grandfather's younger brother and grandmother's next youngest sister: George & Anna Zimmermann Willems.
The photo below was taken around 1916 in Saskatchewan, Canada, most likely in the town of Waldheim.
Note: Elisabeth is wearing a traditional Russian Mennonite head-dress:
Heinrich and Elisabeth, the parents are seated in the center. Seated next to them are their two oldest children and their spouses. Lena, my grandmother, sits next to her father. Jacob, my grandfather, sits next to her. Seated next to Elisabeth in the front row is her oldest child, Cornelius, and his wife, Tina. Standing behind them are all the rest of the Zimmerman and Willems children as well as the spouses of those who were married.
