Deborah: I noticed your posting concerning Harold Seth. He was my grandfather's first cousin. Yes, Harold did marry Clara in 1935 in British Columbia and he died in 1929 in Hong Kong where he had been quite prominent in "business and racing circles" [South China Morning Post/ 23 Jan. 1939.].
He was born in Singapore, not England. His brother's name was Hennesy Seth, not Henry. I'm glad to have the details about Hennesy during the war. A lot of white people suffered under the Japanese, including members of the Seth family.
