I missed this post and so did not respond to it earlier like I probably would have, but you are spot on with the fact that claiming the territory isn't something to be called arrogant. I read a Chinese article about an American couple who joined the Communist's revolution in the 40's and ended up living in Beijing for the rest of their lives. The husband had passed away within the last few years and the wife may be gone as well now. Nobody anywhere can claim that their family's bloodline has been around for thousands of years and have the documents to back it up, it just isn't that possible to keep such a paper trail for so long.
