Clifford Boyson, 66, and his sister Betty Billadeau, 70, were separated as children in Chicago's foster care system.
They reunited on Saturday, Jan. 12, in Davenport, Iowa, after Eddie, the 7-year-old son of Boyson's landlord, looked Billadeau up on Facebook for him, the Associated Press reports.
"I went on Facebook and I typed in Boyson," Eddie told ABC News. "There were a whole bunch of pictures that showed up. One of them kind of looked like Clifford and I zoomed in on it and it started to really look like Clifford, [so] I showed it to my mom and dad."
