Conrad Eichler was born 20 July 1721 in Bischhausen (Eschwege), Kurhessen. His father was listed as Johannes Eichler. He married Maria Elisabeth Apel on 12 August 1756 in Waldkappel, Kurhessen. Maria Elisabeth was baptized in Waldkappel 14 May 1734, the daughter of Johann Heinrich Apel and Anna Elisabetha Jacob. In 1766 they immigrated to Russia, along with Maria Elisabeth’s younger sister Maria Sophia (who was baptized 8 February 1739 in Waldkappel) and are named as passengers on the Russian Ship under the command of Lieutenant Samuel Gibbs from Lubeck, arriving in Oranienbaum, Russia on 31 July 1766. They arrived in Moor eleven months later on 18 June 1767. Apparently Maria Sophia did not survive the trek to Russia. Conrad and Maria Elisabeth recorded in Moor on the 1767 census in Household No. 66.
