Ina Coolbrith was born Josephine Donna Smith in Nauvoo, Illinois, the last of three daughters of Agnes Moulton Coolbrith and Don Carlos Smith, brother to Joseph Smith Coolbrith's father died of malarial fever four months after her birth, and a sister died one month after that; Coolbrith's mother then married Joseph Smith, in 1842, becoming his sixth or seventh wife. No children came of the union—Agnes felt neglected in her unfruitful Levirate marriage, the only such marriage of Smith. In June 1844, Smith was killed at the hands of an anti-Mormon mob. Losing her faith and fearful of her life, Coolbrith's mother left the Latter-day Saint community and moved to Saint Louis, Missouri, where she married a printer and lawyer named William Pickett. Twin sons were born to the couple, and in 1851 Pickett traveled overland with his new family to California in a wagon train. On the long trek, the young Ina read from a book of Shakespeare's works and from a collection of Byron's poems. As a ten-year-old girl, Ina entered California in front of the wagon train with the famous African-American scout Jim Beckwourth, riding with him on his horse, through what would later be named Beckwourth Pass. The family settled in Los Angeles, California, and Pickett established a law practice.
