Only Child Who Found Out His Friend Is His Brother: 'It Was an Immediate Love'

Growing up, Walt Gordy, 37, always wanted a sibling. As an only child too, his friend, Mark Tolson, 36, knew how he felt. But little did both men know that their wish would come true in the form of each other. In September, Gordy and Tolson found out they share the same biological father after taking DNA tests through 23andMe. Since their discovery, Gordy and Tolson have traveled together and their families have shared holidays together.
