Hi... any help re finding an obituary or death date for Isaac would be very much appreciated. Issac McKenney was last recorded as blind with his family @ Third Street, Red Jacket, Houghton, Michigan in 1880 census. His wife Grace was later recorded as a widow in 1897 Calumet Directory so Isaac died sometime between 1880-97, but i've had no luck finding his death. If anyone has access to Calumet Cemetery records i'd really appreciate hearing from you.
