In 1948, two-year-old Clifford Boyson was separated from his older sister when they were placed in separate foster homes in Chicago. 

For nearly 60 years, Clifford has searched for his long-lost sister . . . but he hasn't been able to track her down.

Earlier this month, he asked his eight-year-old neighbor, Eddie Hanzlin of Davenport, Iowa, to search for her online.
