Rev. Douwe Johannes VanderWerp was the son-in-law of Jon Derk and Willemina Brummeler. His wife, Gerritdina Johanna (sister of our 2nd great grandmother Alberdina Brummeler-Telder) wrote a letter to their children “In 1864 your father received a call from Graafschap, Michigan in the U.S.A. He declined the call twice and after receiving it the third time he accepted it. In September 1864 we made the long trip to America….Your father was a rich blessing to many through his preaching, resulting in the conversion of a goodly number of sinners.”
