My Malaysian friend is looking for her brother who was given away for adoption. Her father Tan Kok Seong and her mother Goh Saw Hoon have 5 children:- Tan Chin Tat, born 1947 Tan Chin Choo, born 1950 Tan Chin Lean, born 1951 Tan Chin Han, born 1955. She believes the brother she is searching for was born between 1951-1955 and his name would be started with Tan Chin UNKNOWN. My friend lives in north of West Malaysia on the mainland of what was formerly known as Province Wellesley. She believes her brother was given away to a family in this area or on Penang Island.
