In the Masonic Cemetery here in Trinidad, Colorado, there are two Japanese men who are buried there. One is named Soichi Ishida, who died November, 8, 1910, at the age of 43. Inscription: Born: Aza-Uehara, Nakaharamura, Asagun, Hiroshimaken. The other is Kotaro Ito, age 38, died on April, 29, 1914, as a result of a coal mine accident. Inscription: Born: Nishikurimura, Setuhogun, Hiogo-ken. I don't know if these are your relatives but I am trying to locate any relatives of these two men. What makes it interesting is that the two names you are looking for are also the two names of the men I am looking for. Maybe they were friends or relatives living here in Colorado.
