At the time of writing this biography Brenton was unable to say the name of his birth place because men's business had recently been held there. Knowledge of men's business is not public information. As a child he went to school at the Ernabella Mission (Pukatja). Then as a young man he trained and worked as a carpenter.
He worked as a stockman, did fencing at Mulga Park and Musgrave Park (now Amata). He helped build the boundary fence from Mulga Park to Alpara and rounded up the bullock (cattle) on horse. Brenton had never painted on canvas with acrylics before coming to Tjala Arts in February 2007. Brendan's wife is Iluwanti Ken, who he met at Pukatja. They have three children including Sylvia Ken, who like Iluwanti is an artist at Tjala Arts.
