"... David and Sarah (Stevens) Railsback, with their family, left their southern home and journeyed to Indiana, this being in the year 1807, and they established their home on the Whitewater river in Wayne county, near where Richmond now stands. There aleb Railsback attained to years of maturity and maintained his residence until the 10th of November, 1846. It was then that he came to Marshall county, and purchasing timber land he built him a little log cabin home in the wilderness and began the arduous task of clearing and cultivating his farm. He at one time was the owner of about seven hundred acres, but he divided his estate among his children as they attained to mature years and started out in life for themselves. For many years he served his community as its road commissioner. His political affiliations were with the Whig party and he was a member of the Church of God. The death of this brave and honored pioneer of Marshall county occurred on the 9th of July, 1895, long surviving his wife, Nancy (Barnhill) Railsback, who passed away on the 27th of April, 1874. she was born in Butler county, Ohio, May 29, 1811, and both she and her husband died in Argos. They were married in Marion county, Indiana, January 17, 1828, and of the eleven children which blessed their union, six are now living: William, David, Nathan, U. B., R. C and B. F."
