Does anyone have any real proof that William Grant Jett (31 Jan 1809-03 Nov 1886) is the same William Jett that served in the Confederate Army in Tennessee during the Civil War. I suspect that it may have been a cousin with the same name. William Grant Jett, who was born in Tennessee, had lived in Indiana since at least 1830 and was still living there at the time of his death. His son William Jett (1845 - 04 Mar 1864) who was born in Indiana, served in the Union Army. [William Grant Jett was my 3rd GGF].
