Does anyone know when the "Rigby Star" (now "Jefferson Star") newspaper began?

The oldest microfilmed issues that I've been able to find date back to 1906. Meanwhile, I'm trying to find an article that would have been published in October 1904...that is, if the newspaper was even around then.

From what I've found, it seems the newspaper has gone through several name changes: Rigby Star, The Star, Jefferson County Star, Jefferson Star.

And if the Rigby newspaper wasn't around in 1904, does anyone know what would have been the "go to" paper for Jefferson County happenings?
