She was the daughter of John Hoffman and Maria Sabina Folg. Her date of birth was written in her family's Bible which her father kept. When her father died, he left her 150 acres of land. (He left land to all of his children.)
Around 1775, she married one of her neighbors, John Back. He was the son of Johann Heinrich Bach, who had changed his name to John Henry Back, after he immigrated.
Margaret and John had five children: Elizabeth (born 1777); Anna (born 1779); Sarah (born 1783); Frances (born 1786); and Susannah (born 1790). They only had daughters; they never had any sons, as proven by the Tax Lists in Culpeper County and Madison County, which only showed 1 male (Margaret's husband John). The last Tax List he was seen in was 1793; he died in 1794. Margaret was then listed in the Tax Lists; she had no males living in her house, only her daughters.
Their daughter Elizabeth married John Embry. Their daughters Anna and Sarah apparently never married. Their daughter Frances married Henry Floyd, but she died in 1815. And their daughter Susannah later married Henry Floyd.
After her husband John died, in 1794, Margaret continued to live on their farm for a few years. In 1807, she sold the farm and moved to Rockingham County, Virginia, because her daughter Elizabeth and her husband John Embry were living there. It is believed that two of Margaret's daughters (Anna and Sarah), who had never married, moved there with her. Her daughter Elizabeth and her husband John Embry had moved there, several years before.
Margaret Back then moved onto 50 acres in Rockingham County, along Wolf Run. This land was owned by her daughter Elizabeth and her husband John Embry. On April 10, 1809, Margaret bought that 50 acres, along with another 50 acres, with her nephew Aaron Back (the son of her sister Elizabeth Hoffman Back). The deed indicated that the land was on both sides of Wolf Run, which was just east of the town of Elkton. It is suspected that 50 acres was on one side of the creek, and 50 acres was on the other side of the creek. Margaret continued to live on the 50 acres that she had been living on, and the other 50 acres was for Aaron and his mother Elizabeth (Margaret's sister) to live on, as they were then moving there, because Elizabeth's husband Henry Back had recently died.
Tax records show that Margaret paid taxes on her 50 acres, from 1811 until 1830. She was also seen living there, in the 1820 and 1830 Census Reports; her two daughters were living with her.
It is believed that Margaret died in 1831, because she was not listed on the Tax Lists after 1830. She was probably buried in an unmarked grave in the nearby Elk Run Cemetery.
