The answer is no. Glen Jacobs' character Kane is the brother of Mark Calaway's Character in a wrestling storyline for the WWE (Formerly the WWF). They aren't related in real life. Plus neither Glen Jacobs or his character Kane was EVER related to Mean Mark Callous which was Mark Calaway's character in WCW which is a completely different promotion. Glen is too young to have worked with Mark when he was running that character (1989).
