Heinrich Römer was born on 31 October 1713 in Ettingshausen, just east of Giessen. He was baptized there on 3 November 1713 and married there on 3 June 1738 to Anna Christina Weil. They had the following children, all of whom were born in Ettingshausen: (1) Johannes, born May 1739 & died 2 September 1744 of Diptheria; (2) Michael, born 31 July 1742; (3) Andreas, b 8 September 1745; (4) Johann Jacob, born 16 November 1748; (5) Anna Elisabetha, born 28 February 1751; and (6) Johann Conrad, born 22 October 1752. Heinrich died in Ettingshausen, apparently on 28 March 1754 [although the Ettingshausen Familienbuch records his death in 1714].
Widow Christina Römler and her children immigrate to Russia where she and three sons (Andreas, Jacob, and Johann Konrad) arrive in Krasnoyar on 20 July 1767. They are recorded on the 1767 Census of Krasnoyar in Household No. 96.
