Kevin Jonas SR and Denise Jonas.
Their parents named them as is usually the case. As the parents were called Jonas it seemed logical to call the children Jonas also. They were brought up together and their parents informed them they were brothers as they all had the same parents. The brothers had no reason to disbelieve this so assumed they were, in fact, brothers. When they discovered they had a talent for 'music' they spent a great deal of time thinking of an original name for the band they formed together. After much discussion and debate the settled on the Jonas Brothers as the name of the band.
well there last name is Jonas and they are brothers
"Sons of Jonas", but Kevin came up with "Jonas Brothers".
The Jonas brothers last name is Jonas!
No one knows. I hope I helped. Your friend, Amy!

The Jonas Brothers
They got their name coz Their last name is Jonas and they are all brothers so put them together and you get : Jonas Brothers
Jonas is the last name of the Jonas Brothers, and it is their real last name.
Well they are brothers and their last name is Jonas.
If you mean the individuals, their parents. If you mean the band name, it was Kevin's idea.
