My widowed GM Margareta SEVSHEK, nee ZAKRAJSEK, married Rudolph CHAD
on 14 FEB 1930 at Holy Family Church, Eveleth. At his death 21 APR 1953 his obituary listed, John Chad of Eveleth, and Frank Chad of Yugoslavia, and Mrs. Theresa KOKAL in Yugoslavia. Theresa KOKAL, nee CHAD was born to Ignatiis C'ad & Theresiar SEVS'EK recorded at Sv. Helena Dolsko. This is the only info I have on the surname KOKAL but it does show a family KOKAL in Yugoslavia c.1953. Dolsko is just east of Ljubjana.
