Oda Nobukatsu
Both Ikoma Ienaga, the fourth clan head and his son Ikoma Toshitoyo, the fifth clan head, served Oda Nobunaga with 1900 koku annual stipend. After the Honnō-ji incident when Nobunaga was assassinated, they served his second son Oda Nobukatsu (織田信雄). After Nobukatsu was forced to become a monk the Ikoma clan became rōnin and so became retainers of Toyotomi Hideyoshi.
