Sierra Jo Dominguez (née Baird; formerly Molyneux) (born September 10, 1989) is the second child and first daughter of Sharon Molyneux.

She is the sister of Dakota Baird and Laken Baird.

She is the wife of Mark Dominguez and the mother of their seven children, Khai, Daylon, Asher, Ellyn, Edyn, Brooks, and Merrick.

Early life

Sierra Jo Molyneux was born on September 10, 1989, to Sharon Molyneux. She was her mother's second child, and her mother and adoptive father went on to have one more child after her.

When she was four years old, her mother married her step-father David Baird on September 4, 1994 at Thorncrown Chapel in Eureka Springs, Arkansas. David later adopted Sierra and her older brother Dakota and they both took his last name.

Sierra describes her childhood as being unpleasant and she found comfort in spending time at a neighbor's home. At six years old, she was sexually abused. After many failed attempts to tell her mother, she was finally able to. The man who abused her passed away when she was ten years old. As an adult, Sierra can't remember her life from 1st to 4th grade.

Sierra grew up around horses and had an experience at some point as a child where she was thrown off of a pregnant horse.

Sierra grew up in Carthage, Missouri and attended Carthage Senior High School. She competed in a district-wide competition in carpentry as a high schooler and was the only girl to make it that far. Many of her relatives still live in Carthage, but it is unclear when or why she moved to Arkansas.
