From Dongari Killa in India, from which the word 'dungarees' came.[1] See Etymology of "dungaree"

So it appears blue jeans did not originate in the Americas.
The story I heard was that Levi Strauss ended up with a surplus of the darned stuff and made pants with rivets for miners, not to mention his name and his fortune. And that happened in the U.S.A.
