DeSoto Parish Marriage Records, 1837-1860 lists a "Mrs. Mary Burns" (bride) to "William B. Porter" (groom), on July 1, 1858 (Book A 285). The 1860 DeSoto Parish Census does not list her husband but family #729-750 enumerated Mary Porter, age 45, born NC, keeps hotel; along with William Burns, age 17, born AL, with no occupation but possessed $1500 in real estate and $2200 in personal estate. But no doubt he is Dr. William Robert Burns (1843-1900), son of former Texas Ranger Dr. Robert Burns (d1855) of Logansport, LA. His half brother (Dr) Jacob Smith, b. 2/17/1833 - d. 12/14/1882, m. Ellen Lockert Johnson, b. 10/20/1834 - d. 09/25/1875, are buried in the old family cemetery of Congressman Alvey R. Johnson (1803-1862) of Shelby County (J.B. Sanders (1966) Our Dead: Shelby County, Texas, 1836-1964). Ellen Lockert Johnson (1833-1875), sister of Benjamin Milam Johnson (1838-1915), married in 1857 to Jacob Smith (1834-1882), eldest son of Henry Smith (died 1840) of Marengo County, AL, first husband to Mary Morris Smith Burns Porter (11/21/1813), eldest daughter of Elijah Morris (1791-1866) of Shelby County. By marriage Ellen was a sister-in-law to Captain Levi M. Truitt (1827-1905) and BGen Alfred M. Truitt (1817-1864). Another of the Truitt brethren, Andrew Jackson Truitt (1819-1876) married 1850 to Elizabeth Johnson (1833-1928), niece of Alvey R. Johnson Sr. (1803-1862), hence Ellen Lockert Johnson Smith was also first cousin to the Truitt brethren.
