I have information from several Carney researchers on our King Hiram.He is in the John Carney b. before 1775 d. about 1855 in Lawrence Co., Miss.
King Hiram was b. 1833 in Miss. He served in the Civil War and is Buried in the old Brightwater Cemetery in Choctaw, Alab.He has a Civil War Memorial Marker there.His son you speak of is also buried there - John Wesley Carney b. March 18, 1856 d. October 19, 1941.Buried next to John Wesley is is wife - Martha Emily Bell.
I have photos of these headstones if you would like to see them.I made a trip back there 6 months ago and took the pictures.This cemetery is full of the Carney's, Bonner's and Turner's.
