Andreas Unkefug, son of Johann Georg Unkefug from Eichenhayn, and Anna Barbara Kayser, daughter of Johannes Kayser from Thirrlamm, married 18 August 1766 in Schlitz.
Johannes Winterholder, son of Johann Georg Winterholder from Herchenau, and Anna Margaretha Unkefug, daughter of Johann Georg Unkefug from Eichenhayn, also married 18 August 1766 in Schlitz.
According to Schulze, Eichenhayn is now Eichelhain.
Johann Georg Unkefug and his family immigrated to Russia, arriving in the colony of Boisroux on 17 August 1767. They relocated the following spring to the colony of Meinhard. Father Georg and his family are recorded on an appendix to the 1767 census of Boisroux in Household No. 31. Son Andreas and his family are recorded on an appendix to the 1767 census of Boisroux in Household No. 56. In 1794, Andreas Ungefugt moved from Meinhard to Shaffhausen.
The 1767 census records that both of these Ungefugt families came from the German village of Eichenhayn.
