Harriet Eliza Boynton was born on April 20, 1862 to Enoch and Charlotte Gage (Kimball) Boynton in Groveland, Massachusetts.
Harriet was a first cousin twice removed to Rachel Foster Lurvey (1791-1881), Mrs. John Carroll. Harriet was, therefore, in her own generation a third cousin to the ten children of Jacob William and Rebecca (Whitmore) Lurvey Carroll.
