Katherine; Robeson Household Cutlery is not an area in which I claim any expertise, although I use it almost exclusively every day.
I can, however, provide a clue.
I have owned multiple boxes like that one, although they were for pocketknives, not kitchen cutlery sets.
Some of the boxes are marked, "THE ROBESON CUTLERY CO. ROCHESTER, N.Y.", as is yours.
Others were marked "ROBESON-ROCHESTER CORPORATION ROCHESTER, N.Y. or something similar.
The date Robeson Cutlery Co and Rochester Stamping Works were merged, as stated by Tom Kalcevic in Knives Can Talk!, was 1922.
One can surmise that your cutlery set predates that.
