JOHN A KENT AND JOHN A CUMBER. I am much obliged to you, Mr. Editor, for giving additional circulation to my inquiry (through the medium of the _Athenæum_ of the 19th ult.) regarding the two ancient popular wizards, John a Kent and John a Cumber. I was aware, from a note received some time ago from my friend the Rev. John Webb of Tretire, that there are various current traditions in Monmouthshire, and that Coxe's history of that county contains some information regarding one of these worthies. That fact has since been repeated to me by a gentleman of Newport, who wrote in consequence of what appeared in the _Athenæum_, and whose name I do not know that I am at liberty to mention. I may, however, take this opportunity of thanking him, as well as the transmitter of the curious particulars printed in the _Athenæum_ of Saturday last. One point I wish to ascertain is, whence John a Kent derived his appellation? This question has not been at all answered. Has his name any connexion, and what, with the village of Kentchurch, in Monmouthshire; and why was the place called Kentchurch? To what saint is the church dedicated? and has the name of that church anything to do with the name of the saint? Anthony Munday (or Mundy), in his MS. play (now in my hands by the favour of the Hon. Mr. Mostyn, and by the kind interposition of Sir F. Madden), does not give the slightest clue to the "birth, parentage, and education" of John a Kent. As to John a Cumber, all we learn is, that he was a Scottish conjuror, employed by a nobleman of the same country to counteract the proceedings of John a Kent, who is represented as in the service of Sir Gosselin Denville, a person who appears, from what Munday says, to have had power and influence in South Wales. Now, the name of Sir Gosselin Denville itself suggests a Query; because I find in Johnson's _Lives of Highwayman, &c.,_ fol. 1734, p. 15. (I do not of course refer to it as a book of any authority), that there was a celebrated collector of tribute from travellers who bore that name and rank. He, however, came from Yorkshire, and lived (according to the narrative of Johnson, who had it most likely from Capt. A. Smith, whose work I have not at hand) as long ago as the reign of Edward II. Let me ask, therefore, whether there exist any tidings respecting such a person as a native of Wales, and as the "master" (I use Munday's word) of John a Kent?
