Patricia Ann Spann, 46, and her biological daughter Misty Velvet Dawn Spann, 26, got married in the town of Lawton about 17 months after same-sex marriage became legal in the state of Oklahoma.

To get around the potential snag of their shared family name, Patricia Spann listed her name as Patricia Ann Clayton on the pair’s marriage license application, filed with Comanche County.

For her part in marrying her daughter, two years after she was legally allowed to contact her children following an annulled marriage to her biological son, Patricia Spann will serve time in jail, according to the Oklahoman.

The newspaper reported that she pleaded guilty to felony incest Tuesday, and under a plea deal, the 46-year-old will serve two years in prison followed by eight years of probation. She will have to register as a sex offender following her release.

Incest is punishable by up to 10 years in prison in Oklahoma.

Patricia Spann told child welfare investigators she lost custody of Misty and her two other children before reconnecting with them in 2014. That’s when Patricia and Misty “hit it off,” and started the relationship that eventually landed them both in jail.

Before the pair was arrested, they made their home in Duncan, Okla., about 30 miles from the Texas-Oklahoma state line and less than 20 miles from Lawton, where they were married.

Her children were legally adopted by their paternal grandmother after Patricia Spann lost custody, and she even told investigators she thought her marriage to Misty was legal “because her name was no longer listed on Misty’s birth certificate,” according to the Duncan Banner.

In 2008, according to the Associated Press, Patricia Spann also wed one of her sons. He had the marriage annulled 15 months later, though, citing incest.

The Oklahoman reported that Misty Spann is due back in court next week as part of her plea deal.
