Jan Derk Beukenhorst was born on August 23, 1856. I think his parents were Jan William and Johanna Gertrude (Damkot) Beukenhorst. Jan Derk married a Jawna (?) Kruselbrink. They emigrated to USA and settled in Muscatine, Iowa. His sisters were Sena, Luydia, Johanna, and Henrietta. He had two half brothers who stayed in Holland. Looking for any information on this family and descendants.
