Mlinzi is a descendant of a long line of lions that lived at Zoos Victoria. His maternal grandfather was Maalo - born at Melbourne Zoo in 1999. Maalo’s mother and aunt, Jespah and Gopah, were also born at Melbourne Zoo in 1990 to Juliana. Jespah gave birth to a litter of 5.1 cubs in 2000 - the last of which (Jarrah) died at the Werribee Open Range Zoo in 2020.
