Family #54 in the 1775 Grimm census.
Johann Jacob Fritzler was born at 4:00 a.m. on 19 August 1716 in Kleingartach, Neckarkreis, Württemberg. His sponsors, similar to godparents, were Johann Jacob Gebhart, Johann Jacob Faber, and Anna Catharina Loblen.
Some German records show his first name as Hans, Hanns, or Hannss, which was surprising to me. When I researched what that might mean, I discovered that Hans is the Danish version of Johann.  His name by birth was Johann Jacob, but after moving to Denmark in 1759, he used the Danish version of his first name. Some records list his name as Hans Jacob; that is essentially the same thing as Johann Jacob.
He may have been a brother or cousin of Michael Fritzler Sr. (Fritzler-64). I am still researching this.
Note: The surname Fritzler was sometimes spelled Fritzle.
Jacob Fritzler married Franciska Catharina Eurich on 15 November 1740 in Kleingartach, Württemberg.
Marriage Record 
The couple's first child was born the next year. They would go on to have seven more children by 1761.
The economic conditions in Württemberg mid-1700s were poor, due to war, famine, high taxes and burdensome tithing expected by the local Church. As a farmer, Jacob had difficulty feeding his children and poor prospects for the future.
Starting in 1759, the Danish government offered these disadvantaged Germans a chance for a new life in Denmark helping to farm as yet unfarmable land. Those who chose to immigrate would be given an opportunity for a brighter future via homesteaded land or through a land lottery.
Jacob, Francisca, and seven of their children arrived in the city of Altona, the processing site for Germans immigrating to Denmark, arrived in the town of Schleswig on 04 July 1761.  Their children were:
Note: The Transportation List A24 clearly states that the total number of people traveling to Denmark was nine.  Daughter Anna Maria (Catharina) was born 10 days after the family arrived in Altona.  Also Johann Martin is listed twice; once with his parents and siblings, and separately with his with Christiana. 
The adults took their oath of allegiance to Denmark on 24 July 1761.  In December of that year, the family lived at 3 Christianshof, Christians Thal, in the district of Flensburg.  After nearly four years of unsuccessful farming and after Catherine the Great issued her invitation for Germans to immigrate to Russia, Jacob Fritzler requested to leave Denmark on 24 April 1765. 
Permission to leave the country was granted on 24 May 1765, but it is not clear how soon after that they left Denmark.  Since transportation to Russia didn't officially begin until 1766, the family either remained in Denmark temporarily or moved to another country to await transportation to Russia. At some point during that time, Jacob Fritzler passed away. Only his widow Franciska and her children would make the trip to the Volga Colonies.
By the time the 1775 census was taken for the village of Grimm, his wife was listed as a widow with four older children still living with her. It is not clear whether three of his children perished, or if they were old enough to be married and/or given property separate from their mother's land. A copy of that census entry is shown below for reference purposes.

Two of his daughters were married and living in other households, and son Johann Michael Fritzler had married and was living in family #167.
Jacob Fritzler died prior to 1775, but the exact date and manner of death is not given. There are several ways he may have perished:
