Miller was an early settler of Sugar Grove, Warren County, Pennsylvania, near the New York state border. She was married to Richard Bishop Miller, a prosperous physician and farmer, and had eight children. The entire family and many of their neighbors were abolitionists. Her daughter and son-in-law, Mary Miller McLain and the Rev. William W. McLain, ran the Monongahela House, Pittsburgh's first hotel and a haven for freedmen and abolitionists.[1]
Miller organized Sugar Grove's Female Assisting Society and the Ladies Fugitive Aid Society, sewing clothes for freedom seekers and sheltering freedom seekers at the family home, a colonial farmhouse known as Miller Mansion and an important stop on the Underground Railroad. Miller hosted Frederick Douglass for tea at her home on June 18, 1854, ahead of a speech he gave at the Sugar Grove anti-slavery convention. She and her husband kept detailed diaries of their anti-slavery activities, writing candidly of sheltering freedom seekers and praising Uncle Tom's Cabin.[2][3]
