Natasha du Breuil and Colonel Valentine Burkhardt

I have recently written all I have been able to find out about two amateur naturalists who were active in Hong Kong from the 1940s until their deaths in the 1960s. Their stories uncovered fascinating accounts of life in China between the wars and then of their life together in Hong Kong. They are Natasha du Breuil (ca 1891-1966) and Colonel Valentine Burkhardt (1884-1967). The latter wrote articles (which were read avidly by my wife when the Sunday Post-Herald arrived) and books on Chinese creeds and customs after his life in military intelligence. They lived at 86 Main Street, Stanley, and were involved in a wide range of activites from keeping aquaria and antiques to studying butterflies and collecting stamps. Rather than repeat the long articles here, I provide links to them on my blog, Zoology Jottings. Does anybody have more information?
