SQ - Webster Knows Mystery Cache

There's a blue squiggly at the top - it's a puzzle cache.  The listed coordinates, however, will get you to a nice quiet country road!

This is an SQ - no night caching.  Please be respectful of the graves in the area, and if you see a fallen flag, please put it back in the ground.

Everyone has heard of the Webster Dictionary, but why did this guy get a book named after him?  And does anyone use it anymore?  Look at a normal FriendFace news feed, and you see all kinds of atrocities! (if you don't know what that word means, well, you might need Mr. Webster's product!)  Mr. Webster may well be rolling over every time someone types "C U tomarra, k?"  Sends a shiver down my spine.  Anywho....I thought Mr. Webster's legacy should be refreshed amongst northwestern Ohio.  Go forth & find the answers to the following questions.  You might just learn something!
