This Back/Bach family is not related to Harman Back (aka Hermann Bach), from Freudenberg, Germany. A significant amount of documented research proves this.
In 1994, an incorrect genealogy of this family was published, which claimed that this family descended from Harman Back from Freudenberg, even though there was not one piece of evidence to prove it. Furthermore, everyone in the family already knew the actual genealogy of their family, which is what is shown here. Since then, several Board-Certified genealogists and other prominent researchers and historians have confirmed the actual genealogy of this family, which is what is shown here, by studying numerous primary source documents and other significant records and evidence.
In March of 1806, she had an affair with John Colyer Jr. (FAG #5172556). He was a stranger to the area, and so she did not know that he was already married.
He soon disappeared. She was frantic. She thought he was either "lost in the wilderness" or had been "attacked by wild animals." A few weeks later, she realized that she was pregnant. (She never married John Colyer.)
She had a son who she named Alfred Back. He was born on Dec. 27, 1806. She died, a couple of weeks later, in January of 1807. She was buried next to her parent's cabin along Collier's Creek, near the Poor Fork of the Cumberland River.
***It is possible that, after Mary got pregnant, her parents sent her to live with her older brother John and his wife Catherine, who were then living over in Russell County, Virginia. Being pregnant without being married was considered extremely shameful, back at that time. People who lived near her and her parents knew that she wasn't married. But over in Russell County, Virginia, nobody knew her, and so she could have told people that she was a widow. Therefore, there is a chance that she was buried in Russell County, Virginia, by her brother John's cabin. That would explain why her son Alfred often reported in Census Reports that he was born in Virginia.
