Has 2 daughters: Alena Rose Jonas (b. February 2, 2014) & Valentina Angelina Jonas (b. October 27, 2016) with wife, Danielle Jonas.
A devoted Evangelist Christian, just like the rest of his family, and just like Joe and Nick, wears a purity ring. He's been wearing it since he was sixteen.
Announced his engagement to longtime girlfriend, Danielle Jonas, on July 1, 2009.
He is related to congressmen Charles A. Jonas (1876-1955), and his son, Charles R. Jonas (1904-1988), of North Carolina. Like Kevin, both congressmen were descendants of German immigrants surnamed "Jonas", in the 1700s.
