Betsy was one of the younger children of James and Polly Jennings. It is believed she was born in South Carolina before her parents moved to Kentucky around 1802. When we find her on the 1850 Illinois Jefferson County Census, she stated she was born in Virginia.
Elizabeth Jennings and Dr. John H. Bush were married March 16, 1815. Dr. Bush was several years older than Betsy. We next find Elizabeth on her father, James Jennings, will that was probated in 1834. She is listed as one of the five younger children that his estate was to be divided among.
We find Elizabeth Bush on 1834 Caldwell County, KY records a widow with two sons, George about 13 years old and James about 8 years old.
We do not find Betsy again until the 1850 Jefferson County Illinois Cenus. She is 56 years old living with her daughter Mary Polly's Sinks family in District 10. Betsy is not on the 1855 Illinois State Census, with Mary Polly and her family.
