John Yochum and Katherine (Holtzer) Yochum were my great grandparents. He was born 1861 (Bavaria? Alsace? Germany?) immigrated in 1878 and died 1918. John had a shop at ?th and Carson where he was a butcher. I'm blocked as to his parents and/or siblings. Years ago while visiting his grave at St Michael's, very near Peter Yochum etal, my grandmother said off-handedly that they were not related. I found that odd at the time and still do.
I have also lost track of the Yochums and the Roberts family (John and Katherine would be their ancestors also)who lived in Brentwood later 1900's.
