Johann Georg Schäfer was the son of Eva Elisabeth Schäfer, a widow in August of 1761. I have not yet been able to find a birth record for Johann Georg, so I can't confirm his father's name, nor his mother's last name at birth. When I last checked, there were no Eva Elisabeths, so I suspect she went by Elisabeth, a common name which makes the search more difficult.
Johann Georg arrived in Denmark in August of 1761.  It is unclear if his father passed away on the journey to Denmark or died in his German home town of Rohrbach before the family immigrated to Denmark.
Much of southern Germany had been ravaged by war and famine, and Johann Georg's mother, probably a widow, was concerned about providing for his family, now that she was raising her children alone.
In 1759, Danish King Frederick V invited Germans from Hessen and the Palantinate to help settle the area of Schleswig-Holstein, at that time under the control of the Danes. The king was interested in converting the marsh lands to arable farm land. Germans were known for their good farming skills and for being hard workers, so it seemed like a win-win situation both both Danes and Germans. Johann Georg's mother decided the opportunity to immigrate to Denmark with her family was the right thing to do for her family.
The adults in the family took their oaths of allegiance to Denmark on 30 May 1761. By 08 August 1761, the family was living at 4 Lille Dannemark in the Colony G14, Julianenebene, in the district of Gottorf. The family included:
The marshlands were very inhospitable to farmers. Although the Germans were good farmers with typical farm land, it was far more difficult to convert these former wetlands and grow crops. Most of the German immigrants barely reaped enough to feed their families, let alone to provide food for others in Denmark. When Catherine the Great invited Germans to immigrate to Russia, Johann Georg and his brother Caspar decided it offered them a better opportunity than what was there for them in Schleswig-Holstein.
The two brothers left Denmark on 18 February 1765 and immigrated to Grimm, Russia, a village near the Volga River.  They probably first settled in a different, already established village, like Dobrinka, before finally settling in Grimm. Johann Georg is listed as the head of the family #70 in the 1775 Grimm census.

By 1798, he had passed away. The birth of his youngest child was in 1783, so he passed away between 1783 and 1798. In the 1798 Grimm census, his wife Maria Sybilla is listed as the head of the household. Also listed are two three children. If the couple had any daughters between 1775 and 1780, they may have been already married and living in other households.
