We have recently moved from Hamburg/Germany into Chattanooga, TN. My wife's Maiden name is Undine Heins, her father's name is Martin Dietrich Heins, and his father's name was Wilken, his wife's name Adele. They originated from Fahrendahl, which is a place between the villages of Zeven and Bremervoerde in Northern Germany, formerly part of the Kingdom of Hanover (Koenigreich Hannover).
We know our relatives have moved in several chunks mainly into South Dakota since they used to be farmers. One of my wife's uncles, Hinrich, has visited our relatives in South Dakota a couple of years ago.
