Masazo Sato, from what I have heard from family, is related to or descended from the last shogun, Yoshinobu Tokugawa, but have not been able to find a descendant list online to prove this.
All of Masazo's grandchildren have pictures of the man they believe was their ancestor on their wall. He came over from Japan with money around 1888, and opened a florist shop here in 1890 along with a Japanese Antiques business. He had a partner for many years named Shintato Suzuki.
1918 SATO Masazo president of Nippon Garden Inc. h 166 E 96th New York. He had two children while here, Ruth Sato and Arthur Sato.
Any help on finding out whether he is related to Tokugawa Yoshinobu would be greatly appreciated.
