These may not be in your line, but just in case: In Elmwood Cemetery in Memphis, Shelby Co., TN are the following:
John Metcalf Maury b. July 25, 1868, d. July 10, 1933 and (probably his wife) Flora Turley Maury b. Nov. 15, 1872, d. Sep. 10, 1952. John Metcalf Maury Jr. b. Aug. 6, 1897, d. Aug. 11, 1973; and (probably his wife) Jane Wellford Maury, b. Oct. 4, 1910, d. Nov. 15, 2000.
Also on this Maury family plot is a magnificent celtic cross style monument to the Maury family with elaborate carvings that depict the tweleve desciples, the four gospels and the incarnation.
In another section of the section of the same cemetery are the follwowing graves: William Poston Maury Jr. Sept. 24, 1912 - Sept. 5, 1986 (he was a doctor and he delivered ME at Baptist Hospital in Memphis in 1950) his wife, Marion Hollenberg Maury Aug. 27, 1925 - June 29, 1985.
Dr. William P. Maury's brother: Napoleon Falls Maury, Dec. 16, 1914 - Nov. 28, 1984. Their parents: William Poston Maury, July 21, 1877 - July 11, 1966 and Elizabeth Falls Maury, Sept. 11, 1883 - Feb. 14, 1978.

The Turley, Falls and Wellford families were all prominent local familes. There are some other Maury graves listed in the records at Elmwood but none that I saw that match those you listed. (I volunteer there occasionally giving tours and was there today, so I looked up the Maury names) Hope this might help.
