Simone Biles Family Tree - Parents, Siblings and Husband

Jonathan Owens (born 22 July 1995, St. Louis, Missouri) is an American football safety and the husband of gymnast Simone Biles. He played high school football at Christian Brothers College High School in St. Louis and college football at Missouri Western State University. Undrafted in 2018, he signed with the Arizona Cardinals, then spent 2019 to 2022 with the Houston Texans, 2023 with the Green Bay Packers and 2024 to 2025 with the Chicago Bears, before signing with the Indianapolis Colts in March 2026. He and Simone announced their engagement on 15 February 2022 and married on 22 April 2023, making him the son-in-law of Ron and Nellie Biles.

Ron Biles is the maternal grandfather and adoptive father of Simone Biles, the most decorated gymnast in history, and of her younger sister Adria. After serving in the United States Air Force, where he was stationed at Randolph Air Force Base outside San Antonio, he built a career as an air traffic controller. In San Antonio he met Nellie Cayetano, then a nursing student from Belize, and the couple married and raised two sons, Ron Jr. and Adam. When his granddaughters needed a stable home, Ron and Nellie took them in, and in 2003 they formally adopted Simone and Adria and raised them in Spring, Texas, near Houston. In 2014 Ron and Nellie bought the gym now known as World Champions Centre, where Simone trains. He is a familiar figure in the stands at her competitions, and Simone has long described him simply as her dad.

Silas Charles Cayetano (1925-2010) was a Belizean educator, cooperative official and senator, and the father of Nellie Biles, the adoptive mother of Olympic gymnast Simone Biles. Born on 20 September 1925, he trained as a teacher, graduating from Mico Training College in 1948, and later served as an official in Belize's fishing and agricultural cooperatives before becoming a senator. He married Evarista, a teacher who also ran a grocery store, and they raised four children, Nellie, Jennifer, Silas Jr. and Courine. Education was the family's guiding value, and all four children went on to university in the United States. He died on 18 September 2010. Through his daughter Nellie, Simone and Adria Biles are counted among the Cayetano grandchildren, a connection that has made Simone a source of national pride in Belize.

Simone Arianne Biles (born 14 March 1997, Columbus, Ohio) is an American artistic gymnast and the most decorated gymnast in history, with 11 Olympic medals (7 gold) and 30 World Championship medals (23 gold). At Rio 2016 she won team, all-around, vault and floor gold plus beam bronze; at Tokyo 2020 she won team silver and beam bronze after withdrawing from several finals to protect her safety and wellbeing; and at Paris 2024 she won team, all-around and vault gold and floor silver. Five skills carry her name. She received the Presidential Medal of Freedom in 2022. Raised in Spring, Texas, she and her sister Adria were adopted in 2003 by her grandfather Ron Biles and his wife Nellie, whom she calls her parents, and she trains at the family-owned World Champions Centre. She married NFL safety Jonathan Owens on 22 April 2023.

Adam Biles is a son of Ron and Nellie Biles and, through his parents' 2003 adoption of Simone and Adria, the brother of Olympic gymnast Simone Biles. He grew up in Texas and has been part of the family's gymnastics business, having worked as general manager of World Champions Centre, the training facility in Spring, Texas, that his parents bought in 2014 and where Simone trains. His brother is Ron Biles Jr.

Adria Biles is the younger sister of Olympic gymnast Simone Biles. The two sisters were taken in as young children by their maternal grandfather Ron Biles and his wife Nellie, who formally adopted both girls in 2003 and raised them in Spring, Texas, alongside Ron and Nellie's sons Adam and Ron Jr. Through their adoption, Adria and Simone are legally sisters as well as biological ones, and Ron and Nellie are the parents of both.

Nellie Cayetano Biles is the adoptive mother of Olympic gymnast Simone Biles and her sister Adria. She was born in Belize City, Belize, one of four children of senator and educator Silas Cayetano and his wife Evarista. In 1973, at 18, she left Belize to study nursing at the University of the Incarnate Word in San Antonio, Texas, where she met Air Force serviceman Ron Biles, whom she married. Trained as a nurse, she went on to co-own a group of nursing homes across Texas. With Ron she raised two sons, Ron Jr. and Adam, and in 2003 the couple adopted Ron's granddaughters Simone and Adria. In 2014 Nellie and Ron bought the gym that became World Champions Centre in Spring, Texas, the facility where Simone trains. Her Belizean roots are the reason Simone is embraced as a national heroine in Belize.
