An article by Wilhelm Funk records the following going to Russia:
Samuel Isman, a shoelace maker (Nestler), son of Gottfried Ismann, a shoelace maker (Nestler) in Breslau, & Marg. Magd. Bernhard, widow of Joh. Samuel Bernhard, formerly specialty dealer (Spezereihändler) in Nürnberg, both Lutheran, were married on 10 April 1766 in the sacristy of the Lutheran Church in Wöhrd.
Johann Samuel Ismann, a locksmith (Schlosser), and his wife Margaretha Magdalena settled in the Volga German colony of Warenburg on 12 May 1767. They are recorded there on the 1767 census in Household No. 67 along with stepsons [surname Bernhardt] (Georg, age 18; August Martin, age 16; Johann Michael, age 13).
The death of Samuel Ismann in 1806 is recorded on the 1811 census of Warenburg in Household No. 87.
The 1767 census records that Johann Samuel Ismann came from the German village of Breslau.
There are no known surviving male lines of this family among the Volga German colonies.
