Family
Mia Randall comes from a blended family, with siblings connected through both of her parents’ relationships.
Through her mother, Randi, Mia has two half-brothers: Patrick Mahomes, born in 1995, and Jackson Mahomes, born in 2000, who is Patrick’s full brother because they share both parents.
Through her father’s side, Mia has no publicly confirmed siblings. On Patrick’s father’s side, separate from Mia’s immediate family, Patrick has two additional half-siblings: a younger sister, Zoe Mahomes, born in 2015, and a younger brother, Graham Walker, who has played college football at Brown University.
However, both are considered part of Patrick’s extended family. Despite the 16-year age gap between Mia and Patrick, their mother, Randi, has spoken about their close relationship.
She has said that she once worried the age difference would create distance between her children, but instead found that they developed a strong bond.
Mia is regularly seen supporting her older half-brother at Kansas City Chiefs games alongside their mother.
She has also attended high-profile events, including sitting with singer Taylor Swift during one of Swift’s visits to a Chiefs game.
Despite that visibility, Mia’s mother has described her as someone who deliberately avoids using her family connection for attention.
In one interview, Randi Martin recalled that Mia tells people she takes pictures with her famous relatives rather than emphasizing their relationship, reflecting her desire to maintain her own identity.
Mia is also known within the family as a passionate football fan. Her mother has described her as being more knowledgeable about the game than many casual fans, even recognizing players by their jersey numbers and faces.
