Is there a Williamsport Township in Mahoning County. Or was there a Williamsport in Mahoning County in 1877. I am trying to pin down the birthplace of a relative of my wife. I have Mina Kate (nee Fowler) Brooks being born on 22 Oct 1877 in either PA or Williamsport, Columbiana, OH. She married James Garfield Brooks in 21 Jan 1900 in Industry, Beaver, PA. Thanks in advance.
