Re: FINN family of Liberty, Ohio

John and Mary Ann daughter Mary Ann was my great grandmother. Do not know anything about any brothers or sisters. Mary Ann married Elza Landrum (my great grandfather) and is buried Mather-Pierce Cem. in Jackson County. They lived in Liberty Township, Jackson, County. I remember my great grandmother. I have a picture of her standing on the porch of her house with her dog. Would like to know the dates of her parents birth and death and where they might be buried. Mary Ann is buried on a nice size lot at Mather-Pierce and possibly her parents are there but without a stone. Any help on dates will be appreciated. Thank you.
