I have read many of your informed additions. I have a question about the tokugawa lineage which you have contributed to. Yasuhisa Tokugawa (the current chief shinto Priest for the Yasukuni shrine and kaicho of IMAF) states in his bio that he is the great grandson of the last Shogun Yoshinobu Tokugawa.
The issue is that he is not listed as the current family head. Where does Yasuhisa fall in the current line? Is he in a different Tokugawa clan?
