In "Beauty And the Beast" Martin's mom told him he was her favorite out of his other sibilings. I don't ever remember seeing his other immediate family members. In one episode, we meet his cousins and uncles but not any brothers or sisters.

Do y'all remember anything?

No I don't remember Martin having and brothers or sisters. All those crazy characters on that show were enough. I don't think we could have handled any more.

He did hav some crazy cousins who came to visit him once. They were straight up thugz. mama payne had to leave town when she heard they were coming. LOL
