Marcelles Williams has two older brothers, Max and Macen, who played football at USC and Arizona State. Williams first emerged for California football powerhouse Bellflower St. John Bosco as a sophomore when he recorded 42 tackles and seven pass breakups. He then became a lockdown defender for the Braves in 2022 with 46 tackles and four pass breakups. Williams also had a knack for making big plays at key moments, including two interceptions in the CIF Open Division state championship game against San Mateo Serra. He was honored for his big season by being named to the MaxPreps Junior All-American team.
