On the passenger list for the Hiye Maru in 1935 as I found on FamilySearch.org, Kumakichi Matsudaira was living at 1-30, Kamiomicho, Kanazawa, Ishikawa at the time; he was also listed as the grandfather of Takehisa (John) and Yoshihisa (Michael), both of whom were through Thomas Tokuhisa; the grandsons' names were misspelled as Matsutaira. No mentioning of their maternal grandparents, who as I know were surnamed Umeda.
