I think you ment to type: "Who is in the Jonas Brothers?" If you did, the youngest brother of the band is Nicholas Jerry Jonas. The second youngest/middle age brother in the band is Joseph Adam Jonas. Lastly we have the oldest brother of the band Paul Kevin Jonas ll. Hope I helped. [:
new answer: I don't see why not. He is a Jonas too. Franklin Nathaniel Jonas. He is their brother, a JONAS BROTHER. The band name shouldn't change.
Kevin Jonas was 18 years old when they started the Jonas Brother band.
It was origanally 'Sons Of Jonas'
In the band, yes. In his family, no. He has a younger brother Frankie.
