Hi. My Ggrandfather was born in Sard in 1887, under the name of Rudolf Gluckner (or Gloeckner?). As a young man, he changed his name to Rezso Gabor. Any information on families with these names would be much appreciated, as I know nothing else about him or his family. He was Jewish, so if anyone has had luck in searching the history of Jewish communities in that region, please contact me.
