Georg Heinrich Buxmann was born 6 January 1717 in Überau, a small village southeast of Reinheim. He married to Elisabeth and they had several children, among whom was Johann Georg (born 19 June 1745 in Überau). Georg Heinrich died on 13 January 1760. His widow remarried Kaspar Axthelm, a sock weaver from Überau. The parish register in Überau records that Axthelm "took off for Russia in the night with his wife and 4 step-children, leaving behind many debts, a house, and goods."
Two of the Buxmann stepsons (Georg & Johann Jacob) settled in Müller on 16 August 1767 and are recorded there on the 1767 census in Household No. 12. In 1796, Georg Andreas Buxmann moved from Müller to Schwab.
