Brandon David Jackson (March 12-13, 1957) was Marlon's twin brother. He died 8 to 24 hours after birth because the twins were several weeks premature. The cause of his death was respiratory failure.
His death had a lifelong impact on Marlon, who developed a close bond with his younger brother, Michael, growing up, as he considered him a substitute for his lost twin. When Michael died in 2009, Marlon mournfully requested that he "Give Brandon a hug".[1]
