Doyles on old maps

I realized there are more useful ways I can use the University of Pittsburgh's historic Pittsburg maps. After all the work I did searching for the Doyles in the 1900 Census and confirming that they lived at 1586 Second Avenue, I could probably find them on a map. Now, if only I could determine where 1586 Second Avenue was. I know it is Hazelwood. 22nd Ward. But the maps don't show house numbers. This is going to take some digging...
