N. B.--Inferior portraits by some provincial artist. I conclude Lucas is the surname, and Whittonus indicates his locality; if so, what place? Whilst on this subject, I would add another Query respecting a picture in this house: a very highly finished portrait (small size) by Terburgh, of a gentleman standing, in black gown, long brown wig, and a book on a table by him. "Andries de Graeff. Obiit lxxiii., MDCLXXIIII." Can you tell me anything about this old gentleman? T. F. * * * * * MINOR QUERIES. _Christian Names._--Can any of your correspondents inform me when it became a common practice to have more than one Christian name? Lord Coke says (_Co. Litt. 3 a_): "And regularly it is requisite that the purchaser be named by the name of baptism and his surname, and that special heed be taken to the name of baptism; _for that a man cannot have two names of baptism as he may have divers surnames._" And further on he says: "If a man be baptized by the name of Thomas, and after, at his confirmation by the bishop, he is named John, he may purchase by the name of his confirmation.... And this doth agree with our ancient books, where it is holden that a man may have divers names at divers times, _but not divers Christian names_." It appears, then, that during the first half of the seventeenth century a man could not have two Christian names. Also, at what period did the custom arise of using as Christian names words which are properly surnames? ERICAS. _Lake of Geneva._--The chronicler Marius (in the second volume of _Dom Bouquet_) mentions that, in the reign of the sons of Clotaire, an earthquake or landslip, in the valley of the Upper Rhone, enlarged the Lemannus, or Genevese Lake, by thirty miles of length and twenty of breadth, destroying towns and villages. Montfaucon, in his _Monumens de la Monarchie_, i. p. 63., {407} states that the Lake of Geneva was formed on this occasion: absurdly, unless he means that upon this occasion its limits were extended to Geneva, having previously terminated further east. What vestiges of this catastrophe are now perceptible? A. N. _Clerical Portrait._--May I request the assistance of "N. & Q." in discovering the name of a reverend person whose portrait I have recently met with in my parish? The individual from whom I procured it could give me no other history of it, but that he had bought it at the sale of the effects of a respectable pawnbroker in the village many years ago.
