I'm looking for any information regarding my Romanian ancestors. My grandfather, Arnold (Aronica) Berke (Bercovici changed to Berkowicz changed to Berke), emigrated to N.Y. c.1909 when he was approx. 3 years old. His father's name was Soloman Bercovici (b.1884 in Bucharest), his mother's name was Etta Kahn (b.1883 Jassi Romania). He had 3 older siblings: Leonora, Bernard (aka Bercu) and Sigmund. Does this sound familiar to anyone? I'm a novice at this, so any tips as to how to track down documents or other leads in Eastern Europe would be much appreciated!
