Yoshimune was closely related to the Tokugawa "shōguns". His grandfather, Tokugawa Yorinobu, was a brother of second "shōgun" Tokugawa Hidetada, while Yoshimune's father, Tokugawa Mitsusada, was a first cousin of third "shōgun" Tokugawa Iemitsu. Yoshimune thus was a second cousin to the fourth and fifth "shōguns" (both brothers) Tokugawa Ietsuna and Tokugawa Tsunayoshi, as well as a second cousin to Tokugawa Tsunashige, whose son became "shōgun" Tokugawa Ienobu.
