I have many Dubuque History books ... and one, Dubuque on the Mississippi written by William Wilkie states (and I quote) " Eagle Point Ave ... is now Kaufmann Ave." IF you go down KAUFMANN Ave heading east it turns into East 22 Street and you will Be Right in front of SACRED HEART CHURCH. I also have an 1867 Dubuque City Directory it references Couler ave is between Eagle Point Ave and Diagonal ... if you are familiar with Dubuque you will know Diagonal St is very near KAUFMANN Ave. and nowhere near Windsor Ave. Thank you
