Sources disagree on life dates. Most have 1850-1936 (undocumented), but the tombstone says 1851-1938. Birth year 1851 is also supported by 7 available census reports: most of them have 1851 as 'estimated' birth year (based on age), and the 1900 census for Hillsborough (NH) has explicitely January 1851. Also a 1911 Copyright entry mentions birth 1851.
Alice married twice; her pen name consists of her birth name (Alice Davis) and the surname of both husbands (Simon Odekirk and Albert Greenwood).
