I am looking for information on Matsuo & Mamura sirnames in Japan. My great grandfather was Chiyomatsu Matsuo. My great grandmother was Fayugiku-I Mamura. He was born 12-30-1897 and died 1971. She was born 12-31-1900 and died 09-1986. Know they had at least one daughter, unknown how many other children. Her name is Chizuyo.
Any information would be appreciated. They lived in Sasebo, Japan. And Kagoshima Ken, Japan.
