Family #22 in the 1798 Grimm census.
Family #55 in the 1834 Grimm census.
She was from Rossochi. This was most likely the village known as Franzosen, which was also known as: Franzosen, Pervomaiskoye, Rossochi, Rossoshi, Rossoschi, and Rossotschi.
It could also refer to a town in the Ukraine which was eventually part of the Pale of Settlement. Franzosen was a Catholic village, while Rossochi in the Ukraine would have been Jewish. It is more likely the family was Catholic and lived in the Volga Region, and Franzosen was relatively close to Grimm.
The only Pikners I could find in the census records were Heinrich and Maria Pikner, ages 30 and 26, Catholics farmers possibly from Sterzenbach, who first settled in the Colony of Beauregard, no where near Franzosen. They are listed in the 1767 Beauregard Census.
In the 1798 Franzosen census, it states that Maria Magdalena married Johann Jakob Kling, but there were no other family members living in Franzosen at that time.

Gertrude married Johann Maier (Major) before 1814. Their first child was born in 1815. By 1834, they had two more children.
Since her father inherited his father's estate, including the land on which they farmed, she and her husband continued to live with her parents so that the property would stay in their family. This was especially important since her father passed away in 1823 and her mother would have been left alone to handle the upkeep of their land.
Her married surname was Major, pronounced Maier. Originally [in Germany] it was pronounced and perhaps spelled Maier, but the spelling Major had been used for several generations by the time of the 1834 census.
