Background
Van Deman was a daughter of Joseph and Martha (Millspaugh) Van Deman. She was born in South Salem, Ohio, the fourth and youngest child of her father's second marriage when he was already sixty years of age. She had two older half-brothers.
Her one sister was nine years her senior; of her two brothers, only one survived infancy. The Van Deman (originally Vandeman) family was of German origin.
Her grandfather, John, who was born in Virginia in 1757, fought in the Revolutionary War and received a land grant in Ohio in return for his services. Here Esther was born and grew up in a comfortable farm house. Her mother had a Dutch-Scottish background and brought her children up in the Presbyterian faith. They all attended the South Salem Academy.
When the sister married in the early 1870's the family followed her to Sterling, Kansas. As a child, Esther showed considerable musical ability and for a time seriously considered embarking upon a musical career.
