Yagyu Hyogonosuke

A little while ago, I posted up some information on the "Drying Pole" about the Yagyu Shinkage Ryu started by Yagyu Sekishusai. Information on certain members of the Yagyu family is often more readily available, such as Yagyu Munenori (Son of Yagyu Sekishusai, started the Edo line of Yagyu Shinkage Ryu). Unfortunately, it's harder (at least for me) to find material in English about others, such as Yagyu Hyogonosuke (grandson of Yagyu Sekishusai, carried on the Owari line of Yagyu Shinkage Ryu). I'm very interested in learning more about Yagyu Hyogonosuke. If anyone has come across any information about him (books, web pages, video, etc.) in any language, please post it here. I would greatly appreciate it.
