Evans married Roy Rogers on New Year's Eve 1947 at the Flying L Ranch in Davis, Oklahoma, where they had earlier filmed the movie "Home in Oklahoma". The marriage was Rogers' third and Evans' fourth but was successful; the two were a team on- and off-screen from 1946 until Rogers' death in 1998. Shortly after the wedding, Evans ended the deception regarding her son Tommy. Roy had an adopted daughter, Cheryl, and two biological children, Linda and Roy Jr. (Dusty), from his second marriage. Together they had one child, Robin Elizabeth, who died of complications of Down syndrome shortly before her second birthday. Her life inspired Evans to write her bestseller "Angel Unaware". Evans was very influential in changing public perceptions of children with developmental disabilities and served as a role model for many parents. After she wrote "Angel Unaware", a group then known as the “Oklahoma County Council for Mentally Retarded Children” adopted its better-known name Dale Rogers Training Center in her honor. She went on to write a number of religious and inspirational books, and she and Roy appeared many times with Billy Graham in Crusades all over the country, singing gospel songs and giving their testimony. Evans and Rogers adopted four other children: Mimi, Dodie, Sandy, and Debbie.
