His mother who is known as Patricia Nombuyiselo Noah is Black and of Xhosa ethnicity.
In 1992, Noah’s mother, Patricia Nombuyiselo, was married to Ngisaveni Abel Shingange, and they had two sons together, Andrew and Isaac.
Trevor and his mother were both physically abused by Shingange, and the couple divorced in 1996.
In 2009, after she became engaged to Sfiso Khoza, Shingange shot her in the leg and through the back of the head, stopping when the gun jammed; she survived as the bullet went through her head, avoided the brain and all major nerves and blood vessels, exiting with minor damage to her nostril.
When Noah confronted him over the phone about the shooting, Shingange threatened his life, prompting Noah to leave Johannesburg for Los Angeles.
