Martha Ann "Mattie" Gay was born in 1837, the sixth of 12 children of Johan "Ann" Stewart (Evans) Gay and Martin Baker Gay, a farmer. Her father moved the family around several southern states before, in 1851, deciding to emigrate from
Springfield, Missouri, to Oregon along the Oregon Trail. The crossing took five months, and the family eventually settled in
Lane County, Oregon. During the trip, Martha kept a diary of the family's trials and adventures, and she continued keeping this diary afterwards, right up until her death. In 1871, she married widower James Alfred Masterson. They had three children together, two of whom died young. The couple moved around a good deal and separated after twenty years, and Martha spent her later years with her only surviving child, her daughter Frances. Masterson died in
Eugene, Oregon, at the end of 1916. ==Publications and legacy==
