The Barnum Family 1517-1904 incorrectly shows her as a child of Americus V. Barnum (1845-1901).
When Mabel Addie Barnum was born on December 21, 1877, in Seattle, Washington, her father, Perry, was 24, and her mother, Sarah, was 22. She married John Westwood Green on 19 Nov 1896 in Seattle, and they had four children together. She then married George Russell Hallock (1877-1956) on August 21, 1918, in Everett, Snohomish, Washington. She died on July 5, 1935, in her hometown at the age of 57. She was cremated and her ashes were buried next to Alice Sprague, her father's cousin's wife.
