Hello, I don't know if my Cincinnati Horans are the same, but I figured I'd say hi.
My grandfather John Rae Horan. He was born in 1907 in Birmingham, AL but he moved to Cincinnati sometime in the late 1920s. John married Dolores Clements in 1931 and they had 6 children.
John Rae's father John Edward Horan was born in Louisville, Kentucky around 1872. From what I've gathered, in the my case of my Cincinnati Horans, is that they came from Ireland in the 1840s to Louisville, KY then they moved to Birmingham, Al and then wound up in Cincinnati, OH. By the 1940s they also resided in Michigan.
Well, I don't know if that's useful, but I thought I'd share.
