I believe Johannes was my great-great-grandfather, born May 30, 1826, probably in Switzerland. (His confirmation certificate fell out of an old family Bible I inherited.) I believe he was from the canton Graubünden (Grisons, in French), and that he came to the USA with his wife and young children in the early 1870's. One of the children was Emma (or Emarita). She married John Coyle, and lived in Walla Walla, WA, until her death in 1954. Other Buehlers also lived in that area. I would like to know what year Johannes came to the US, and to what state.
