The final "e" was dropped at some point, although there are records of county newspapers using the "Blaine" spelling through at least 1868. Early in the 1800s, Blaine's mill came into the possession of William Douglas, who had a post office established with the name "Douglas' Mills". A subsequent owner of the mill, Anthony Black, had the name of the post office changed to "Multicaulisville", after the mulberry tree, in which he had a financial interest during a speculative bubble in the tree. Lots were platted for sale in 1846 and the name of the post office was changed to "Blain".At one time, Blain was noted for being the smallest borough in Pennsylvania to own its own water plant and electric street lighting system.
