Marenda Grayson

Marenda Grayson (d. June 1997) was the wife of Jonas Grayson and the amither of Dick Grayson. The Grayson family moved to Gotham sometime before June 1997 because of their Roma status and a desire for Dick to have a better life. Shortly after their move, however, Marenda and Jonas were killed by Red Hood in front of Dick, who was then held captive by Red Hood for a week. Dick was eventually rescued by Bruce Wayne as Batman, and later adopted by him and his husband, Tony Stark.
Dick has admitted before that he does not have many memories of his biological parents.
