Kevan Lannister is Lord Tywin's younger brother (the non-dead/missing one). He's frequently Tywin's battle commander when Twyin cannot be in the field with the Lannister Army. He also is Lancel's father - the Lannister cousin who was banging Cersei when Jaime went into the field. One of his other sons was killed by Rickard Karstark - a page or squire - held prisoner by the Starks at Riverrun. It's why Robb Stark beheaded Lord Rickard.
