The late Jim Murphy would be the best source of information on this company. You can read his article here: https://kb.osu.edu/dspace/bitstream/handle/1811/38883/Rosevilles_Progressive_Pottery.pdf?sequence=1.
It is doubtful that the company had any connection to Roseville Pottery (who made all of their art ware in Zanesville) other than the ways in which all Roseville pot shops were related in some form by second cousins and drinking buddies.
I assume it has the full bottom marking doesn`t it ?? Can you post a pic of the pot and the bottom marking ??
There is little available on this company due to its short life !! I did find that it was purchased in 1903 by James Miller, Charles Golden and James Armstrong but I did not find from who it was purchased !! It was located in Roseville, Ohio !! There may be a connection between the Roseville pottery we all know and Progressive but I did not see a direct reference to it !! The pottery from Progressive is fairly rare so additional research would be needed to establish any value it would have !!
Someone mentioned that a bean pot was on Ebay recently,, was that yours ??
