William R. Hoel (7 March 1824 – 23 May 1879) was an officer in the United States Navy during the American Civil War. A native of Butler County, Ohio, Hoel was a Mississippi River steamboat pilot when he entered the United States Navy 19 October 1861. Family life Hoel's first wife was Mary Riley, daughter of Daniel Riley, of Cincinnati. His second wife was Elizabeth Hunt, eldest daughter of Dr. Samuel Pancoast Hunt and his wife Elizabeth Thomas, of Morrow, Warren County, Ohio. Captain Hoel and Elizabeth Hoel had two children: Sarah Elizabeth Hoel and Rion Hoel.
