James Ryoichi Ishihara (涼一 石原) Name

So how did we come up with James Ryoichi Ishihara (涼一 石原) name?
James is Grandpa Ishihara's first name. It is also father's first name, although father goes by his middle name Alec. Hence, why Ryo will go by his middle nickname, instead of James the Third :)
Ryo means refreshing. Ichi means first son.
