I was wrong about him owning the bar w/ my grandfather. I talked to my dad last night and he said Carl worked in a glass factory. It was John who owned half the bar. My father said he can remember going to the hospital to take Mary, Carls wife for therapy.
My great grandfather was Alexander Fahrner, one of Carls brothers.
I am going to give my grandmother a call she knows just about everything when it comes to who's related and how. I'll let you know what I come up with.
