Ohio Revised Statute 1.49 provides:
If a statute is ambiguous, the court, in determining the intention of the legislature, may consider among other matters:
(D) The common law or former statutory provisions, including laws upon the same or similar subjects;

Pierce v. BRUSHART., 153 Ohio St. 372 - Ohio: Supreme Court 1950 states:
It is universally recognized that a person may adopt any name he may choose so long as such change is not made for fraudulent purposes.

On this subject 38 American Jurisprudence, 610, Section 28, states:

"In the absence of a statute to the contrary, a person may ordinarily change his name at will, without any legal proceedings, merely by adopting another name. He may not do so, however, for fraudulent purposes. In most jurisdictions, a change of one's name is regulated by statutes which prescribe the proceedings by which such change is to be accomplished."

And it has been held that where a person is as well known by one name as by another, the use of either name is sufficient. Gillespie v. Rogers, 146 Mass., 610, 16 N. E., 711.

Bobo v. Jewell, 38 Ohio St. 3d 330 - Ohio: Supreme Court 1988 states:
In Ohio, names may be changed either by resorting to a judicial proceeding or by the common-law method of simply adopting a new name, so long as the change is not made for fraudulent purposes. Pierce v. Brushart (1950), 153 Ohio St. 372, 380, 41 O.O. 398, 402, 92 N.E. 2d 4, 8.

In re Change of Name of DeWeese, 148 Ohio App. 3d 201 - Ohio: Court of Appeals, 3rd Appellate Dist. 2002 states:
Ohio has traditionally recognized two ways in which a person may accomplish a name change. First, absent an intent to commit fraud, a person may change his name at common law by simply adopting another name. Pierce v. Brushart (1950), 153 Ohio St. 372, 41 O.O. 398, 92 N.E.2d 4; Dennis v. Ford Motor Co. (1997), 121 Ohio App.3d 318, 699 N.E.2d 993.

State v. Hayes, 119 Ohio Misc. 2d 124 - Ohio: Municipal Court 2002 states:
In essence, this case reveals a situation where an individual is going by more than one name. It has long been established in Ohio that a person may change his or her name either by petitioning the probate court[2] or by the simple expedient of adopting and using a new one. Both procedures are equally valid in the eyes of the law. A person may change his name at any time or even use several different names, so long as he does not do so for a fraudulent purpose. Bobo v. Jewell (1988), 38 Ohio St.3d 330, 333, 528 N.E.2d 180; State ex rel. Morrison v. Franklin Cty. Bd. of Elections (1980), 63 Ohio St.2d 336, 339, 17 O.O.3d 420, 410 N.E.2d 764: Pierce v. Brushart (1950), 153 Ohio St. 372, 380, 41 O.O. 398, 92 N.E.2d 4; In re Name Change of DeWeese, 148 Ohio App.3d 201, 2002-Ohio-2867, 772 N.E.2d 692.

In re Wurgler, 136 Ohio Misc. 2d 1 - Ohio: Court of Common Pleas, Probate Court 2005 states:
At common law, anyone may assume any name he or she wishes so long as taking the name is not for fraudulent purposes. Pierce v. Brushart (1950), 153 Ohio St. 372, 41 O.O. 398, 92 N.E.2d 4. In the absence of a statute to the contrary, a person may change his or her name at will, without any legal proceedings, merely by adopting a new name. This most commonly occurs when some wives take the surnames of their husbands. They establish their new names by custom and practice—not through a court order.

McCaskey v. SANFORD-BROWN COLLEGE, 2012 Ohio 1543 - Ohio: Court of Appeals, 8th Appellate Dist. 2012 states:
Further, people may adopt any fictitious name they choose so long as it is not done with fraudulent purpose or against public policy. In re Wurgler, 136 Ohio Misc.2d 1, 2005-Ohio-7139, 844 N.E.2d 919 (P.C.).

MATTER OF HCW, 123 NE 3d 1048 - Ohio: Court of Appeals, 12th Appellate Dist. 2019 states:
The probate court confirmed that H.C.W. understood that he had a common law right to "go by whatever name you want to,"
