John Grayson was a business partner of Owlman.

John Grayson and his family ran The Grayson Circus after it was "inherited" from a clown named Anthony Zucco, whom John Grayson had murdered. Most of the acts that he had performing at the circus were black mailed by him and his family. The Circus was in actuality a front for their money laundering operations, they often visited Gotham in which John had several business transactions with Thomas Wayne.
