The History of Hendricks County (Chicago: Interstate Publishing, 1885)--Guilford Township, pages 618-619
Elias Hadley, deceased, was one of the early settlers of Hendricks County. He was born in Chatham County, N.C., Aug. 5, 1809, a son of Jeremiah and Mary Hadley. When he was three years of age his parents moved to Butler County, Ohio, and subsequently to Hendricks County, Ind., and settled in Guilford Township, where they both died. Oct. 14, 1829, Elias Hadley was married, in Butler County, Ohio, to Miss Cox, daughter of Mordecai and Nancy Cox, a native of Butler County, born in 1814. After his marriage he settled on a tract of wild land which is now the site of Plainfield, but at that time was heavily timbered. He cleared and improved a farm, which he subsequently sold and bought one north of Plainfield, where he lived till 1874, when he rented his farm and moved to the village and lived retired from active business till his death, Dec. 8, 1884. The farm contains 180 acres of valuable land, all under cultivation. To Mr. and Mrs. Hadley were born sixteen children, six sons and ten daughters, twelve of whom are living--S__, Hiram, Nancy, Mary, Jane, David, Enos, Emma, Susan, Addie, Oscar and Arthur. Mr. Hadley was a member of the Christian church fifty years and his wife is a member of the same denomination.
