That information could contain some clues. Were John and Frances her sons by George Karstetter or by Mr. Frost? Do you know if she had other children? Sorry to ask so many questions, but last night I searched some censuses and couldn't find anyone named either Edith Frost or a listing for Edith and George Karstetter in Oregon or Washington. Perhaps Edith used a middle name or nickname. Could they have been living in a state other than Oregon or Washington?
