Searching for any living relatives of the Eberhardt/Kovary of Arad, Romania (originally from Germany and Austria). My father's name was Ludwig Eberhardt (later changed to Luis Ludovico Eberhardt), was born in 1892 in Arad, Santa Ana, region of Transylvania, during the Austro Hungarian Empire. Lost contact with his family there, after the Iron Curtain. His father's name apparently was John or Johann, his mother's was Maria (?), he had a sister named Teresia, and a brother.
