Kevin was born in Lynwood, California, on January 18, 1955, the third child of Bill Costner, a ditch digger and ultimately an electric line servicer for Southern California Edison, and Sharon Costner (née Tedrick), a welfare worker. His older brother, Dan, was born in 1950. A middle brother died at birth in 1953. His father's job required him to move regularly, which caused Kevin to feel like an Army kid, always the new kid at school, which led to him being a daydreamer. As a teen, he sang in the Baptist church choir, wrote poetry, and took writing classes. At 18, he built his own canoe and paddled his way down the rivers that Lewis & Clark followed to the Pacific. Despite his present height, he was only 5'2" when he graduated high school. Nonetheless, he still managed to be a basketball, football and baseball star.
