Seventy-year-old Betty Billadeau and her younger brother, Clifford Boyson, were placed in separate foster homes as young children in Chicago a long, long time ago.

 Clifford, who lives in Davenport, Iowa, had been searching for his sister for nearly six decades but had turned up nothing.

That all changed this week when his 8-year-old neighbor found the long lost sister in about five minutes -- on FACEBOOK!

Young neoghbor Eddie  made quick work of solving the mystery using Betty's maiden name. The siblings were reunited by videophone this week and will have a face-to-face reunion this Saturday when Betty drives to Davenport on Saturday.
