Darryl Winslow is the brother of Carl Winslow, Calvin Winslow, Walter Winslow and Frank Winslow and the son of Estelle Winslow and Samuel Winslow. Like Carl's other brothers Walter, Frank and Calvin not much is known about him. It was never said where he lives or whether or not he is married or not. If he was married he doesn't have any kids considering Richie is the only known nephew of Carl. He is mentioned only once in the very first episode where Carl says Darryl owes Carl for helping getting him into college.
Darryl was mentioned to live out of state in The Party, evident when Carl went the wrong way in trying to use a shortcut to get to his 40th birthday party and was cited by Highway Patrol.
