My great grandfather's name was 英袞裳 Ying Gun-Shang, and my grandfather's name was 英朝彥 Ying Chao-Yen. My grandfather left China during WWII, and my father, 英錕頤 Ying Kun-Yi, was born in Indonesia. Since they have all passed away, I have already lost contact with my relatives in China or Indonesia. If your granduncle has some clue, that would be nice. Thanks!
