I recently began to think about the Funakoshi family and wondered to what extent any of them, aside from Giko, were involved in karate.
I have read that Gichin's eldest son was quite an adept, but had an unfortunate gambling problem. He was also the rallying point for the Shotokai following Gichin's death. What ever became of him and his karate?
Also, did the elder Funakoshi teach his grandchildren?
I would appreciate any help answering these questions.
