On envelope containing pictures:
Frau Hermine Schneider-Hunziker, Ober Huber F2, St. Zurich Switzerland.
After searching I believe the man to be Rudolf Schneider, her husband.
I have not found a blood tie yet with either of these people. The letter was sent to my Grandmother Eliza Anna Gubler, or her mother Anna Mary Elizabeth Huber Hafen, who is a Gygax descendent. Annie possible knew these people from when she lived in Switzerland and had joined the LDS Church. Frau Schneider was also a member of the church in that area.
