Whose ideas did Jefferson draw upon while drafting the Declaration of Independence?

I would think it would be Thomas Paine. It was primarily the ideas of Thomas Paine that Jefferson drew upon while drafting the Declaration of Independence, since in "Common Sense" (one of Paine's writings), Paine had explained why independence from Britain was necessary. 

Hope this helps!
