Heinrich Jacob Ochsenhirt, son of Sebastian Henrich Ochsenhirt & Anna Margaretha Reichard, was born on 12 June 1729 in Düdelsheim. He was married there on 24 February 1752 to Maria Elisabeth Eyring, daughter of Johannes Eyring of Bruderdiebacher Hof.
They arrived at the port in Oranienbaum on 4 July 1766 along with 4 children: Catharina (age 13), Johann (age 11), Elisabeth (age 3), and Wilhelmina (age 1/2). It appears that his wife and two youngest children died, as he arrived in Messer on 18 June 1767 and is listed there on the 1767 census in Household No. 36 along with his wife, Philippina, and 3 children: Anna Katharina (age 15), Johann Adam (age 13), and Anna Maria (age 1/2). The oldest two children are identified as belonging to his first marriage, and the youngest to his second marriage. Per the 1798 Census of Messer, Philippina's maiden name is Willmann.
