_Penn Family_ (Vol. iii., pp. 264. 409.).--In No. 75. of "NOTES AND QUERIES" for April, 1851, inquiry is made "to whom William Penn, the eldest son of William Penn (the founder), was married, and also to whom the children of said son were married, as well as those of his daughter Letitia (Mrs. Aubrey), if she had any?" William Penn (the son) married Mary Jones, by whom he had three children, William, Springett (who died without issue), and Gul. Maria. William had _two_ wives, Christiana Forbes, and Ann Vaux. By Miss Forbes he had a daughter, married to Peter Gaskell, Esq.; and by Miss Vaux a son, Springett, who died without issue. Mrs. Aubrey (Letitia Penn) had no children. EDW. D. INGRAHAM. Philadelphia, July 4. 1851. _Bummaree_ (Vol. iv., p. 39.).--I have no doubt that this word is derived, as so many of our _market_ terms are, from the French, _bonne marée_, fresh fish. "Marée signifie toute sorte de poisson de mer qui n'est pas salé; _bonne marée, marée fraîche, vendeur de marée._" _Dict. de l'Acad. Franc._, voce. C. _Miss or Mistress_ (Vol. iv., p. 6.).--The indiscriminate use of "Miss" and "Mrs." to unmarried ladies is often very perplexing. The "Mrs." was not, as M. S. supposes, always accompanied by the Christian name for unmarried ladies; and the custom lasted at least as late as the reign of George II. Pope in his letters (about 1719) mentions "Mrs. Lepel" and "Mrs. Bellenden," maids of honour. The examples are innumerable, but the _latest_ instance I remember is the Duchess of Queensbury addressing Patty Blount in 1756 as "Mrs. Blount;" though, no doubt, Patty was, by _that time_, entitled to what is called _brevet_ rank. C. _Book Plates_ (Vol. iii., p. 495.; Vol. iv., p. 46.).--MR. PARSONS, I observe, confines his inquiry to English book plates. On that point I cannot at present offer him any information but I can to a certain extent confirm his views with regard to the use of them in foreign countries, having now before me the plate (a woodcut) of Erhardus à Muckhenthall--probably in modern German, Erhardt von Muckenthal--dated 1634. It consists of his armorial bearings, surmounted by a helmet, &c., apparently indicative of nobility; but the tinctures not being expressed, I cannot give the blazon. The charge on his shield seems to be intended for a lamb salient. F. S. Q. In the Surrenden Collection there are several loose impressions of Sir Edward Dering's book plate, bearing date 1630. It is a very elaborate one, and of a size adapted only for a folio volume; one of them is now before me, with the date most clearly and distinctly marked. L. B. L. Miscellaneous.
