Sarah Eastman Draper was born on February 25, 1840, in Illinois to Ichabod and Catherine Draper. Her father was a farmer who owned $2,000 of real estate in 1850. Sarah grew up and attended school in Elk Grove, Illinois. Her father probably died in the 1850s, and her mother married Timothy Hubbard soon afterward. In 1860, Sarah was living on Hubbard’s farm in Elk Grove. Theodore Kellogg began courting her in the early 1860s, and they corresponded while he served in the Union army during the Civil War. They got married in Chicago on June 26, 1867, and they had at least three children: Henry, born around 1868; Timothy, born around 1873; and William, born around 1878. They lived in Chicago for several years before returning to Elk Grove. Her husband worked as a laborer and farmer, and the family owned $350 of personal property in 1870. Sarah died in Illinois on February 15, 1899.
