Mississippi Constitution Art. 15, § 274 provides:
The laws of this State now in force, not repugnant to this Constitution, shall remain in force until amended or repealed by the Legislature, or until they expire by limitation. All statute laws of this State repugnant to the provisions of this Constitution, except as provided in the next three sections, shall continue and remain in force until the first day of April, A. D. 1892, unless sooner repealed by the Legislature.

Coplin v. Woodmen of the World, 105 Miss. 115, 62 So. 7 (1913) states:
In Snook’s Petition, 2 Hilt. (N. Y.) 566, it was said that a man’s name is the mark by which he is distinguished from other men. At common law a man could change his name, in good faith, and for an honest purpose, and adopt a new one, by which he could be generally recognized. In the case of Smith v. U. S. Casualty Co., 197 N. Y. 420, 90 N. E. 947, 26 L. R. A. (N. S.) 1167, 18 Ann. Cas. 701

Marshall v. MARSHALL, A MINOR, 93 So. 2d 822 - Miss: Supreme Court 1957 states:
We fully realize and appreciate the fact that at common law any person of mature years can voluntarily change his name without the necessity of a statute such as we have in Mississippi, provided the change is not for a fraudulent purpose and does not interfere with the rights of others. That rule is recognized in the same section of C.J.S. from which we have quoted above and a full and interesting discussion thereof is found in the case of Smith v. U.S. Casualty Co., 197 N.Y. 420, 90 N.E. 947, 26 L.R.A. (N.S.) 1167, 18 Ann. Cas. 701.
