Heinrich Hirschenhaÿn, son of Carl Hirschenhaÿn from Hain-Gründau, and Anna Maria Dietrich, daughter of Peter Dietrich from Mittelgründau, were married in Hain-Gründau on 8 August 1765.
They immigrated to Russia, settling in the Volga German colony of Messer on 18 June 1767. They are recorded there on the 1767 Census in Household No. 46. The surname in Russia appears to be Hergenhein.
It is not clear how Heinrich is related to Elisabeth Hirchenhaÿn also from Hain-Gründau, the wife of Jacob Repp who settled in Huck.
