The History of Hendricks County (Chicago: Interstate Publishing, 1885)--Union Township, pages 729-730
Hiram Rains, one of the enterprising business men of Union Township, was born in October, 1824, in Fayette County, Ind. His parents, James and Elizabeth Rains, were natives of North Carolina, who settled in Marion County, Ind., in 1828, and remained there until their death. Our subject received a fair education, and Sept. 25, 1851, he was married to Miss Sarah Owens, a daughter of Benjamin and Esther Owens, of this county, the former being deceased. Two children have been born to them--Martha A. and Flora. Flora is deceased. Mr. Rains besides being quite an extensive landowner, has large lumber interests with his brother, Levi Rains, in Tennessee. In 1870 he came to Hendricks County, Ind., and for many years was extensively engaged in the manufacture of building material, having in his employ at one time as many as thirty workmen. His works were at Rainstown, which place was called after its energetic founder.
