Johann Christoph Heuck was born May 12, 1807 at Gessin, Germany, later he lived at Malchin, Germany. He immigrated into the US April 4, 1869 at NY with wife Marie Charlotte Friederike Westphal and two daughters Elisabeth Marie Catharina and Wilhelmine Marie Adolphine. The Heucks at Gessin, Mecklenburg, Germany were farmers since the 1650ies.
If the Heucks in Denmark have any relationship to the Gessin
Heucks is not known to me.
