Rev. William Sims was the brother of Rev. James Sims and Elizabeth (Sims) Earnest, and an uncle to John Sims and Nancy (Sims) Kelley. All eventually migrated to Sangamon County, Illinois. The family of Williams Sims has been more difficult to research than those of his siblings. Most of his descendants seem to have added an extra "m" to Sims, going by the Simms name.
SIMS, WILLIAM, (uncle to John Sims) was born in Virginia, taken when young to South Carolina, married there to Miss Welch. He came to Sangamon county among the earliest settlers, and raised a family of nine children, none of whom now live in the county. He was for many years a pioneer local Methodist preacher of limited education, but remarkable for piety and good common sense. He died in Knox or Henry county, Illinois, in 1859.
