The search data I used for Newspapers category in Licking Co. Ohio was:
1)Last name: with exact option
2)Any Event: 1920 +- 5 years with exact option
3)More Keywords, two words: "Company name" with exact option AND with quotes.

I'm getting late 1950 and 1960 hits when I'm trying to search in the 1915 to 1925 range.

Howdto I restrict the search results for the time span I want? I'm looking to discover when the small company started, by whom and maybe when it ended but I don't have a firm date yet.
