Better yet, I found his obituary - "Luther Pruitt Dies, Ill Month," Journal Gazette (Mattoon, Illinois), August 31, 1942, p. 1.

It says that he was born on February 28, 1865, in Breckenridge County, "the son of Mr. and Mrs. George M. Pruitt." It also lists "a brother John of Breckenridge, Ky." and "a sister, Mrs. Susan Nichols of Breckenridge, Ky." That may help identify his parents.
The sister Susan ties nicely with your census record.
