The maiden name of William Carl Heiden's wife, Mary, was Rambow. Her parents were Heinrich and Wilhelmina (Milhan) Rambow and the earliest ancestor we have found was Nicolaus Rambow who was born in 1754 in Gross Wokern, Mecklenburg-Schwerin, Germany.

Projecting the ancestors chart out to a child born in 2010 would account for nine generations and would make Nicolaus that person's sixth great grandfather.
