Alexander Kuomin Jhin (born January 6, 1979 in San Mateo, California) was a child actor who played Adam in the Barney and the Backyard Gang videos. He was absent in Campfire Sing-Along because he felt ill that day, and was replaced by Jeffrey, who was played by Jeffrey Lowe. However, he returned in the rest of the Barney and the Backyard Gang videos, after recovering. Like most of the others, very little is known about Alexander. He never appears in Barney & Friends, as he moved out of the area before the show began, and was replaced by John David Bennett, II. Currently, Alexander lives in San Francisco, California, and is married to Diana Chan.
