I have been reading the book "Legacies of the sword" by Dr. Friday and I have noticed the deep connection with Takeda Shingen and the minamoto clan. I also notice that this is the same lineage claimed by several daito ryu groups (minamoto clan not kashima shinryu), could there be a connection? Afterall, noone seems to know where the jujutsu (hiden mokuroku) of daito ryu comes from for sure (asayama ichiden ryu?)
I was just wondering if there could be a connection between these arts as the book mentions the kashima shinryu cnnection to the minamoto quite a bit. Perhaps Dr. Friday could help with this?
