Those chubby little cheeks belong to Laura J. Raymer, the daughter of Charles and Nellie Raymer, who was born in August of 1888 in Minnesota. The date on the back of this photo says it was taken in 1891, making Laura three years old when she posed for it. In 1900 Laura lived with her parents and two older brothers Henry and Louis in Minneapolis. Charles was a bookseller by trade and operated his own store. By the time of the 1910 census the family had moved on to Spokane, Washington where Charles was still selling books.
I have been unable to find any trace of Laura after the 1910 census in which she was 21 years old.
