It's difficult to pin down her last name at birth. It's also difficult to know if she used her first or middle name as her everyday name. According to the 1834 census she was 55 years old, making her born in 1779. That year could be plus or minus one, depending on when the census was taken and the actual month of her birth. Here is a list of the only women born in Grimm that match her description:
Family #47 Margaretha Elisabeth Albrandt 1778
Family #45 Louisa Margaretha Heide 1778
Family #91 Elisabeth Margaretha Faas 1779
Family #41 Katharina Margaretha Klar 1779
Family #147 Katharina Margaretha Reizenstein 1779
Family #19 Anna Margaretha Wolf 1780
Family #32 Anna Margaretha Schott 1780
Family #20 Elisabeth Margaretha Schaefer 1780
Based on proximity, there are still several of the women who lived quite close to the Brungradts when the 1798 census was taken. The Brungardts were family #29.
The closest families to them from the above list are the Schotts (#32), the Wolfs (#19) and the Schaefers (#20), all who had daughters with the middle name of Margaretha.
Of the women born in 1779, only Katharina Margaretha Klar (#41) lived in close proximity to the Brungardts.
The only woman with the first name of Margaretha was Margaretha Elisabeth Albrandt (#47), still in close proximity but born in 1778.
Note: The 1834 census adds a T to the last name Brundgardt, her married surname.
In the list of family members in the 1834 census, there is Andreas Albrandt living with the Brungardt family. A footnote states that Andreas was Wilhelm's brother-in-law, married to his sister, Barbara. This is a potential clue in helping to determine the maiden name of Wilhelm's wife, Margaretha. Andreas Albrandt had a sister named Margaretha Elisabeth Albrandt, who is one of the women listed as possibly being his wife.
I looked back at the 1798 census, and the two families can be found in #29 and #47. In family #29, Wilhelm Brungard Senior is the head of the household. Also living with him were his son, Wilhelm Ludwig, his daughter, Anna Barbara, and her husband Andreas Albrandt.
Andreas was one of 15 siblings, one of whom was Margaretha Elisabeth Albrandt. Because of the size of his family, it makes sense that he would live with his in-laws family after his marriage.
By 1798, Wilhelm Brungard senior was 73 years old and his wife Anna Maria Hess was 63. There were seven children in the Brungard family, and only two of them were boys. By 1798, only two children were left living with Wilhelm Brungard Senior and his wife, and he probably needed all the help he could get farming his land so it wasn't taken away from him. The two children remaining were a son and a daughter, and I believe they married two of the Albrandt siblings, Andreas Jr. and Margaretha Elisabeth.
