I have recently been asked by a woman in NY, whose husband is searching for his long lost relatives in Singapore, to help him locate his only remaining family. As he was really young when his grandfather moved the entire family, except for his dad, from Chao Zhou, China to Singapore, he has no recollection of his grandfather's name except for his last/family name. At that time, his dad was at odds with his grandfather so he refused to make the move with his own family. However, when his grandfather was settled in Singapore and had made a fortune from the rubber plantation business, his grandfather sent his youngest uncle to China to persuade his dad to join them in Singapore. Again he refused. Eventually his father lived to regret this decision as his entire family either died from the famine or from the war, leaving him orphaned. Somehow, he moved to Vietnam and then to NY where he met his wife. His wife had informed me that he has been having a nagging feeling of locating his remaining family when he had a dream of his dad asking him to search for them. Since hearing this, I feel really compelled to help him locate his uncles (most likely in their 80s). The only clues to this puzzle are his last name Chang and a detail of his grandfather being a prominent rubber plantation owner.I believe the good news are that there are not too many families in Singapore named Chang and the probability of a Chang family owning a rubber plantation should be relatively small. However, I am not sure if his last name Chang will remain Chang when his grandfather immigrated as I had been informed that Teo is a possible name change for the Teo Chews (the natives of Chao Zhou). I know this is really a hunt for a needle in the haystack so any help will be great. Thanks!
