Samuel Churchill moved from Virginia to Kentucky when he was eight years old. He owned 415 acres of land along Beargrass Creek. The Churchills enslaved thirty-six individuals whose labor created economic advantage and comfort for the family. He had an interest in horse breeding and was president of the Louisville Association for the Improvement of Breed of Horses. Samuel Churchill was one of seven founding trustees of the Oakland Racecourse in Louisville in early 1832, which was located on fifty-one acres of land purchased from Samuel and Abigail Churchill, as well as from other landholders. His sons, John and Henry, inherited land from Samuel, which they leased to his nephew Meriwether Lewis Clark Jr., founder of a new racecourse known today as Churchill Downs.
Abigail Oldham Churchill came from a lineage of wealthy and prominent early Louisvillian settlers. She was just two years old when her father, Colonel William Oldham, died in the Battle of Wabash. Her mother, Penelope Pope, a twenty-two-year-old widow with four children, remarried into the Churchill family. In 1802, two weeks after her fourteenth birthday, Abigail married Samuel Churchill, her step-father's twenty-four-year-old brother. She gave birth to their first child when she was fifteen and had a child almost every other year over a span of thirty years. She had her last of fifteen children when she was forty-four years of age.
