My grandfather was Joahannes Olahborn 1879 in Szatmaar region, died 1961 in Detroit, MI. Married Fransceca Rissavy had children Charles, John, George, Olga, James, William and Julianna. Brothers Imre and Zsigmund(?) Zsigmund may have emmigated to South America. Johannes emmigrated in the early teens.My Uncle Billed visited relatives in Szatmaar in the early 60's.
Any information is appreciated. I know that the Olah name is very common. He moved to McKeesport, PA and later to Fairfax, WV and worked as a coal miner before moving north to Michigan.
