Randy Sandknop of Baker City holds the 123-year-old journal she found in mid-January in a Baker City parking lot. (Jayson Jacoby/Baker City Herald)Randy Sandknop stood in a Baker City parking lot, reached down and plucked from the pavement a 123-year-old mystery. There are details — a wedding anniversary and the date, April 29, 1903, that her baby, Frances, was born. June 2: “Aileen cut her 19th tooth upper left hand side.”On June 3, “the baby” becomes Frances, courtesy of her father. “Ben named the baby Frances,” that day’s entry begins.
