Andrew Jackson [SEP] Legal career and marriage
The two were separated in 1790. According to Jackson, he married Rachel after hearing that Robards had obtained a divorce. Her divorce had not been made final, making Rachel's marriage to Jackson bigamous and therefore invalid. After the divorce was officially completed, Rachel and Jackson remarried in 1794. To complicate matters further, evidence shows that Rachel had been living with Jackson and referred to herself as Mrs. Jackson before the petition for divorce was ever made. It was not uncommon on the frontier for relationships to be formed and dissolved unofficially, as long as they were recognized by the community.
