From the North Avondale Neighborhood Association:
"Businessmen such as Andrew Erkenbrecher, Samuel Pogue, Frank Herschede, Barney Kroger all built homes on these winding streets around the turn of the century. Many of these residences were and still are some of finest examples of residential architecture in Cincinnati. Italian Renaissance, English Medieval, Greek Revival and other styles can be found here."
Photos are from a May 2005 Cincinnati Preservation Association home tour. Some of the homes shown were open to the public that day. I do not have specific historical information on the homes at hand. However, I might be able to dig something up if enough people were interested.
