Maryland Constitution, Declaration of Rights provides:
We, the People of the State of Maryland, grateful to Almighty God for our civil and religious liberty, and taking into our serious consideration the best means of establishing a good Constitution in this State for the sure foundation and more permanent security thereof, declare:
Art. 5. (a)
(1) That the Inhabitants of Maryland are entitled to the Common Law of England

Torbit v. State, 102 Md. App. 530 - Md: Court of Special Appeals 1994 provides:
Maryland recognizes common law name changes. Stuart v. Board of Elections, 266 Md. 440, 446, 295 A.2d 223 (1972). As the Court of Appeals stated in Hardy v. Hardy, "a person may adopt any name by which he wishes to become known, as long as he does so consistently and nonfraudulently." 269 Md. 412, 415, 306 A.2d 244 (1973) (citations omitted). This fact, however, does not preclude appellant from changing his name pursuant to Maryland Rules BH70-75 and Maryland Code (1957, 1994 Repl.Vol.), Art. 16, § 123. Neither the statutory nor the common law method is to be interpreted as the exclusive manner in which a name may be changed. Klein v. Klein, 36 Md. App. 177, 181, 373 A.2d 86 (1977); Hall v. Hall, 30 Md. App. 214, 222, 351 A.2d 917 (1976). "In Maryland, a person may change his name under the common law rule or through a judicial proceeding as he desires." Hall, 30 Md. App. at 222, 351 A.2d 917.
