==Sir Keith Park== 
 Please help a poor puzzled American who doesn't quite grasp the subtleties of the British Empire and Commonwealth. 

 I read Park's bio and noted your change of allegiance for him. I followed the links, and note that New Zealand did not seem to achieve independence until 1947. To me, it seems that Park's allegiance was actually the British Empire because New Zealand was not yet independent. (A pause here to dodge brickbats, if I am mistaken in any of this.) 

 I make the above surmise not to be contentious, but because it bears on an ongoing problem I have while writing biographies on World War I flying aces. A large proportion of RFC/RNAS/RAF aces are from New Zealand, Canada, South Africa, and other Commonwealth countries. I have been stating their allegiance as being to the British Empire because their home countries were under the control of the United Kingdom. I admit, I may be mistaken in this approach–hence this note. Any enlightenment you can share will be welcome.
