Paul McIntyre was a very well know member of the Singapore community who, among various interests, was a highly skilled chess player. He died in Singapore at the age of 76 (b.1860) and his funeral took place on Christmas Day, 1936. His wife died about seven months previously (June 1936). He had been with the firm of Boustead and Co. for 34 years
His only surviving son was Dr D. McIntyre who also attended the funeral of Dora May McIntyre who died in May 1937, wife of Frederick Stewart McIntyre who died in Singapore in 1939.
There were 'several surviving daughters' who may or may not have been married by the time of Paul's death. It's just possible that Paul's brother was Christopher A. McIntyre who was based in Penang and another noted chess player. Also in the Penang chess club was a Mr. D.J Hagerty, a name you may recognise. It's possible that Frederick Stewart McIntyre was the first of three sons of C.A.McIntyre following on from five daughters born before the boys. Best guess for the DoB of Frederick is 1884-1885 as there were two further sons, the last of whom (Colin Adair) was born shortly before their mother died in 1891.
The wife of my great uncle (a school teacher in Penang) was Hilda Mary Stewart McIntyre, second of the 5 daughters, born in 1874. She could have been an older sister of Frederick S. McIntyre. Hilda's son was named Charles Frederick Stewart who went to England at the age of 17 and eventually joined the Merchant Navy as Ship's Radio Officer.
