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 Aug 1765. The couple settled in Messer, and is reported there on the First Settlers List in Family #46. The birth location of their daughter Katharina, age 1-1/2 on the First Settler's List, is unknown. It is not clear how Heinrich is related to Elisabeth Hirchenhaÿn, the wife of Jacob Repp, also from Hain-Gründau, who settled in Huck. The surname is spelled Hergenhein in later records.
