The Suzuki family from Atsumi County in Mikawa had long served for the Tokugawa shogunate, many of whom as vassals of a hatamoto (direct retainers of the bakufu, which is a form of Japanese feudal government headed by a shogun) or a fudai daimyo (a daimyo in hereditary vassal to the Tokugawa family), although none of the members became a daimyo (Japanese feudal lord).
鈴木の家は三河の渥美郡の出で、大名にこそなっていないが、旗本や譜代大名の家臣として多数を占めており、古くからの徳川の家臣である。
