hey Dave, check this out (from a San Soo Website):

(it doesn't link directly, you have to got to the "San Soo" option in the main menu and then click on lineage - they also have a tree with Sifu on it)
Chan Tai Shan
We include the late Chan Tai Shan because he was:
1) A practitioner who included Chan Siu Hung's son, Chan Sai Mo, and cousin to Chan Siu Dek, in his own training lineage
2) A tough American practitioner who taught in New York City Chinatown
3) Held by Chinese martial arts historians and the Chinese government, and noted in Inside Kung Fu Magazine, to be one of China's "National Treasures"
Nothing would thrill us more than to see Losifu Chan Siu Dek one day also honored in this way, serving to further legitimize his family art, our art, Kung Fu San Soo.
