After Masayoshi, since his grandson, Seijiro Satoyoshi (清次郎了能) was too young to succeed, his second son, Kozaemon Kazumune (小左衛門一宗) assumed the third headship of the Ko school, and later Satoyoshi started the Ko Seijiro family (Kosei school) separately.
正能の後は嫡孫清次郎了能が幼少であったため、二男小左衛門一宗が三世を襲い、後に了能は幸清次郎家（幸清流）を興して別家した。
