Ronnie Dunn's first grandchild walked into the world on Johnny Cash's birthday (Feb. 26). Huxton Wayne Dunn was born to Dunn's son Jesse, who the singer revealed is a teacher in Sacramento, Calif. Dunn announced the pending childbirth near Thanksgiving 2011, and was so excited he could barely speak. The family plans to call the new baby Huck, making him the second Huck born in a country music family. Brad Paisley's oldest son William Huckleberry also goes by that name.
