The following information is from my McCann family folder (descendants of Daniel McCann and Margaret LaPointe):
John Henry Mishler died: April 30, 1937 place unknown, probably near Spooner or Springbrook WI. burial:Earl Cemetery, Earl WI
Louisa (McCann) Mishler died: August 24, 1930 Spooner, Washburn Co. burial:August 27, 1930 O'Neill Creek Cemetery, Eagleton, Chippewa Co. WI
I do not have notes to indicate which records may exist:death certificates, funeral parlors, or obituaries, except for the listing of Louisa Mishler's burial in O'Neill Creek Cemetery.
I'm always looking for additional leads on the earliest McCanns in Ohio and Pennsylvania to check out and I'd like to hear from you if you find items on those early McCanns which might be of interest to me.
