Brief history
Not all the history is known, and what little has been passed down has no documentation and may or may not be 100% accurate.
Grand Master Jia Qiwa, "Beautiful Seventh Child," was the child of a frowned-upon union of a Chinese and a possibly Japanese parent.
Born in 1864 in the Western territory of the United States (Probably Nevada now). Parents left their homeland, came to the USA, and worked on the construction of the railroads.
Both parents were said to be accomplished martial artists. (The exact systems are unknown). However, there are similarities to many systems from Japanese, Chinese, and Okinawan systems.
Jia Qiwa is said to have begun training her first pupils around 1897. She died in 1945.
A few of her students carried on the teachings (and refined or personalized along the way, I am sure).
