Johann Friedrich Flath was born 4 August 1743 in Mümling-Grumbach, near Höchst im Odenwald.
He and his wife Eva Margaretha arrived in Russia on 13 Sep 1766. It appears that Eva Margaretha must have died during the journey to the villages, because Johann Friedrich's wife is listed as Maria Magdalena on the First Settler's List. They are reported in Frank in Family #95.
