Bouvier's Law Dictionary, Revised 6th Ed (1856):

ADDITION. Whatever is added to a man's name by way of title, as additions of estate, mystery, or place. 10 Went. Plead. 871; Salk. 6; 2 Lord Ray. 988; :1 WUS. 244, 5. 2. Additions of an estate or quality are esquire, gentleman, and the like; these titles can however be claimed by none, and may be assumed by any one. In Nash v. Battershy (2 Lord Ray. 986 6 Mod. 80,) the plaintiff declared with the addition of gentleman. The defendant pleaded in abatement that the plaintiff was no gentleman. The plaintiff demurred, and it was held ill; for, said the court, it amounts to a confession that the plaintiff is no gentleman, and then not the person named in the count. He should have replied that he is a gentleman. 3. Additions of mystery are such as scrivener, painter, printer, manufacturer, &c. 4. Additions of places are descriptions by the place of residence, as A. B. of Philadelphia and the like. See Bac. Ab. b. t.; Doct. Pl. 71; 2 Vin. Abr. 77; 1 Lilly's Reg. 39; 1 Metc. R. 151. 5. At common law there was no need of addition in any case, 2 Lord Ray. 988; it was, required only by Stat. 1 H. 5. c. 5, in cases where process of outlawry lies. In all other cases it is only a description of the person, and common reputation is sufficient. 2 Lord Ray. 849. No addition is necessary in a Homine Replegiando. 2 Lord Ray. 987; Salk. 5; 1 Wils. 244, 6; 6 Rep. 67.
