This census list starts at the top with Maria's father, Johann Heiden who was born April 19, 1776 in Nienhagen. Her mother, Sophia Tessenow was born on November 10, 1787. A sister, Sophia was born in October, 1807 followed by Maria on July 25, 1811. Her brother, Friederich was born on January 20, 1815 and the last child Johann Heiden came along on January 25, 1818.

Also listed is a woman named Christina whose maiden name is also Tessenow and could possibly be Maria's aunt...but we don't know for sure.
