There was a real Charles Daly who used his name on imported guns. He died in 1899 and the name passed out of the family in 1919. Since then, the Charles Daly name has been used by several companies associated with the firearms business, primarily importing.
Given the dates, it seems likely that the original Charles Daly might have been involved in the company that had manufactured or imported your shotgun. Take the barrels off and look at the bottom and also at the water table (the flat part of the frame under the barrels) for proof marks, especially an oval with the letters E L G, the Belgian proof mark.
