I am trying to discover the exact location of the Old Bishop School in about 1910. A Detroit Directory of 1890 has the school on Winder between Hastings and Rivard. The Sanborn map of the area [[1897 vol. 4 sheet 20) shows no Bishop School--only the Everett Elementary School on Fort Ave. E. There is no 'Winder' between Hastings and Rivard. Another source puts the school on Marion Street between Hastings and Prospect. I cannot find Marion or Prospect on any Sanborn map. I feel like I am missing something very obvious here, but I just can't find the location of the Bishop School! Could anyone direct me to a map that has the school on it, or to information that positively locates the school?
