Long ago T. V. Soong proposed to Aunt Jo, who was quite an Irish beauty in her day. The proposal was problematic. Aunt Jo was a devout Catholic and Soong was a Methodist.
Later Soong's sister married Generalissimo Chiang Kai-shek and Soong became an influential Kuomintang politician. Soong negotiated somewhat successfully with Stalin for support in the early days of the Sino-Japanese war. Apparently, Stalin wasn't as tough a nut to crack as my grandmother when it came to letting her Catholic sister marry a Methodist.
