Johann Christian Seifert was born in 1755 in Baden-Durlach. During that time, Germans were suffering from war and famine, and had difficulty providing for their families. His father had a difficult time supporting his family.
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. Eager to provide a better life for their family, his parents decided the opportunity to immigrate to Denmark was too attractive to pass up.
They departed Germany on 02 June 1761 with a group of other emigrants under the direction of Johann Peter Hornus.  The group arrived in the city of Schleswig on 06 June 1761. There were five children in his family: 
On 08 August 1761, the family lived at Number 11 Frisch auf in Colony G16 Prinzenmoor in the district of Gottorf.  Three years later on 10 November 1764 they lived at Number 8 Auf dem Brinck in the same district. 
The marshlands were very inhospitable to the 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 Christian's parents decided it offered them a better opportunity to provide for their family.
The family left Denmark on 22 November 1765 and are included on a list of German Danes bound for Grimm, Russia.

Those early years in Grimm were difficult, too. Many immigrants did not survive the journey to the Volga. Others were attacked by the Cossacks from the Ukraine and other local bandits and tribal people. One researcher tells of 1,573 settlers being kidnapped in 1774; only half were freed and the rest were killed or made slaves.
It was during this time frame that his father Johann Christian Seifert passed away. It's not clear exactly how he perished, but hundreds of German settlers lost their lives during battles that occurred during the early years of settlement in the Volga colonies. He was very likely one of them.
By the time of the 1775 census, Johann Christian's mother Augusta Maria had remarried Adam Schneider.
1775 Grimm Census 
Only Johann Friedrich and two other siblings were still living with their step father and her at that time:
His two eldest sisters, Eva Catharina and Maria Louisa, were old enough to marry and were probably living with their husband's families.
He married first the widow Ursula Eberhard, but it does not appear that they had any children. By 1798 Ursula had passed away and Christian was remarried to Elisabeth Knorr. The couple had a one-year-old daughter.

By the time of the 1834 census, the only listing for him was to note his death.
1834 Grimm Census 
There is no mention of his widow or children. There were no other Seiferts listed in the 1834 census. His widow was 16 years younger than him and probably remarried after his death. Any descendants he has in Grimm would be through his daughter Elisabeth Seifert Seifert-288 or any other unknown daughters he may have fathered before 1825. If they exist, they may be listed with their mother and her second husband, unidentified for now, in the 1834 census.
