John Funk Duerksen was born in the same village where his father Jacob Johann was born. The same village settled by John's grandfather Johann Johann (19 yrs) and great-grandfather Johann Cornelius (54 yrs), both of whom had come from Schweingrube Prussia. John was baptised in Klippenfeld, about fourteen miles north of Alexanderthal. John's great-grandfather died 8 years before John was born but his grandfather was alive until shortly after his birth.
John's father and the rest of his immediate family emigrated to Lehigh, Kansas in 1884. John stayed in Alexanderthal until 1887, when at the age of twenty-four, he followed the family to Kansas. His seven children were all alive when in Corn, Oklahoma, near the end of his life, he wrote of his family's history. Those pages are held in the Marcellus Duerksen folder in Fresno's Hiebert library. These are included:
"I, John F. Duerksen, was born in Russia in the village Alexandertal on July 25, 1863 on Thursday. In a short time, I was dedicated to the Lord by Br. Jacob Jantz, Friedensfeld. The man was interesting to me, and I observed him closely. He is already well founded in the service of his Lord, old and well experienced in the service of his Lord. I was baptized on April 30, 1879, in Klippenfeld in the Talmand. My parents are Jacob and Katherine (born, Funk). Jacob was born May 2, 1840. Katherine was born June 14, 1844. Both were born and reared in Alexandertal. The parents of my father were John and Helena (born Boldt) Duerksen. Both born in Prussia. Their parents must have lived near Danzig. The parents of my mother were Peter Funk and Julianna (born, Fenski). Both born in Prussia. My grandmother was about 19 years old when she left the Lutheran Church and joined Gnadenfeld Mennonite Church. My grandmother's brother died in the war against Napoleon in 1815. The parents of my wife were Abraham and Katherine (born Dueck) Warkentin."
