The Watanabe family maintained the family status of joshi (superior samurai) in the Tahara Domain and was granted 100 koku through generations, but since his father Sadamichi was an adopted son, his salary was reduced to 15-people buchi (or 27 koku when converted to koku in the Tahara Domain) and the actual income was only 12 koku because of the financial difficulties of the domain.
渡辺家は田原藩の中でも上士の家格を持ち、代々100石の禄を与えられていたが、父定通は養子であったために15人扶持（石に直すと田原藩では27石）に削られ、加えて折からの藩の財政難による減俸で実収入はわずか12石足らずであった。
