The two books that I have are entitled "Seiei-Kan Ju-Jitsu Vol I and Vol II", copyright 1994 with text by Bo Kimley and Donald Madden. I believe there was a time when Mr. Madden and Sensei Kimly teamed up together. It was Mr. Kimly that brought his own Ju-Jitsu program and syllabus to Mr. Maddens' dojo, but somehow the name "Seiei-Kan" became attached to it instead of the name of Mr. Kimly art from Sweden.
I don't know if he is still connected with Madden's group but just a few years ago I sat in and watched a Ju-Jitsu class at the Chillicothe dojo and it was taught by Heather Madden.
This is a bio of Bo Kimly from the United States Ju-Jitsu Federation website:
