Beginning with the 1900 through the 1921 Polk city directories, I found Ammi Mitchell as the resident of 2057 Glenwood Avenue.  During these years, Mr. Mitchell was with the Northern National Bank.  His biography may be read on page 599 of Maumee Valley, Toledo and the Sandusky Region Vol. 3.  His wife was Florence (Au) Mitchell who died June 26, 1913.  According to the 1900 city directory, Mary Puhl was the domestic while Anna Kromair served that role in 1910 along with Amerlia Marquet.
