I have posted a set of links of videos of arts that the founding fathers studied. These art ryu mentioned in
Hidden in Plain Sight
Chapter 1. The Chinese Connection
Kito-ryu - This is obviously connected with the Kodokan's Koshiki no Kata - this group is the last that asserts to practice Kito-ryu - I believe the lineal connection is partially broken, and the kata reconstructed.
Yoshin-ryu - Toby Threadgill, Takamura-ha Shindo Yoshin-ryu
Tenjin Shinyo-ryu (Kubota line)
Tenjin Shinyo-ryu (Shibata line) -
NOTE: Ueshiba Morihei briefly studied this

Horikawa Taiso & Horikawa Kodo
Shibukawa-ryu
Ueshiba Morihei
See above for Tenjin Shinyo-ryu. He also briefly studied judo.
Goto-ha Yagyu Shingan-ryu kenjutsu
Goto-ha Yagyu Shingan-ryu bojutsu
Goto-ha Yagyu Shingan-ryu yawara - Ueshiba studied this appr. 2x a week for four years previous to his entry into Daito-ryu
Yagyu Shinkage-ryu - Ueshiba audited this through Kisaburo Gejo. He adopted several kata and turned them into his aiki-ken which he taught to Tomiki Kenji and later, Hikitsuchi Morio, among others.
Kashima Shinto-ryu - Ueshiba observed his son and another deshi train in this for several years - and adopted several of the kata into the sword training in Iwama. NOTE: Ueshiba did not study Kashima Shin-ryu, a very different school.
Kukishinden-ryu bojutsu - I was not able to find a video of the Kukishin-ryu solo bojutsu form through the Kuki family line.. Most of what is up on the web is Bujinkan derived - and that is not relevant to the discussion. I have theorized that, given some overlap in techniques, and Ueshiba's connection with the Kuki family (even teaching at their dojo), part of the inspiration for his solo jo form was through these kata.
Sagawa Yukiyoshi - studied Kogen Itto-ryu. I was not able to find any videos on the web.
