That's really neat! I live very close by and know exactly where that ball park once was. The Covington Police Department once boasted Bill McQuerey as a patrolman after his playing days were with Cincinnati, Detroit, Kansas City, Syracuse, and Washington were through. He was killed while chasing a suspect across the suspension bridge across the Ohio River in 1900.
The Kenton County Library has a librarian that writes features for their website and does displays on local baseball. He may be able to help you pinpoint an exact date and get the newspaper stories from it. You can get his contact info from this article:
