Misty Velvet Dawn Spann, left, pleaded guilty to incest in November after she was accused of marrying her birth mother, Patricia Spann, 42.
The mother lost custody of her children -- who were later adopted -- when they were little. She and Misty "hit it off" when they reconnected in 2014, Patricia later told investigators.
Patricia thought the marriage was legal because her name was no longer on Misty's birth certificate, records say. Patricia is also charged with incest and will face trial in January 2018.
