Family #50 in the 1798 Grimm census.
1798 Grimm Census 
Her maiden name was secured from the name of her mother who, as a widow, continued to live with her son-in-law after her daughter's death. Her mother's name is included in the 1798 census.
We don't actually know her birth year; the year above was an estimate based on the age of her husband. The only Schroeder family in Grimm was the Martin Schroeder family #127 in the 1775 census. Unless there were fertility problems, couples that married soon found themselves expecting their first child. I don't have a copy of the 1767 census for Grimm, so I can't tell if Johannes was documented as married by that year. What we do know is that he married a woman with the last name Schroeder and they had their first child in 1783.
She could have been Anna Margaretha Schroeder Schroeder-2241, the eldest daughter of Martin and Anna Katharina Schroeder, family #127 in the 1775 census.
She would have been a young mother at 16, but that was a frequent scenario during those early years in the Volga region of Russia. Her husband would have been 11 years older that she was, which is also not unheard of but probably more unusual because of her young age. The Schroeder and Becker families lived close to each other during the 1775 census, families #127 and #130, but Johannes was not listed in that specific family, although it is suspected that Jost and Johannes were brothers.
One of the Johannes Beckers in the Kulberg Reports was traveling as a single person; he was the only one of the two who survived the trip from Oranienbaum to the Volga Colonies. He may have lived with his brother Jost in Grimm and seven years later married one of the neighbor girls. For more information on Johannes Becker.
I am keeping a separate spreadsheet of all the women in Grimm and who they married. At this point, I don't have her matched up to a husband, so this works in favor of the above-mentioned scenario. If I find that she was in fact married to someone else, I will update my notes here.
She is not specifically listed in the 1798 census, but her children are identified as those of Johannes Becker's deceased wife. Her eldest child was born in 1783, and her youngest child in 1792. She was deceased before 1797 which allowed her husband to remarry and have a child with his second wife in 1798.
