_Barnard's Church Music._--Can any of your readers point out where John Barnard's first book of selected church music, folio, ten parts, 1641, is to be found? The writer knows of the imperfect set at Hereford Cathedral, a tenor part at Canterbury, and a bass part in private hands. Dr. Burney makes mention, in his _History of Music_, of having sought diligently throughout the kingdom, but could not find an entire copy. Perhaps some of your correspondents may kindly favour the writer with a list of its contents. AMANUENSIS. _The Nelson Family._--In Burke's _Commoners_, under the head of "Nelson of Chuddleworth," it appears that _William Nelson_ of Chuddleworth, born in 1611, had by his second wife, the daughter of John Pococke, gentleman, of Woolley, among other children, a son named _William_; but of whom no further mention is made. Can any of your Norfolk or Berkshire friends state whether this son _William_ ever settled at Dunham Parva, in Norfolk?--as, by so doing, an obligation will be conferred on your occasional correspondent FRANCISCUS. _Letters to the Clergy._--In the _Diary of Walter Yonge_ (published by the Camden Society), p. 24., is the following: "16 Dec. 1614. This day the Ministers of this Diocese (Exon) were called before the Bishop of Exon, who read letters from the Archbishop, the effects of which were, that every minister should exhort his parishioners to continue together the Sabbath Day, and not to wander to other preachers who have better gifts than their own pastors, but should content themselves with the Word of God read and Homilies. 2. That all should kneel at the receiving of the Sacrament. 3. To declare unto their parishioners that it is not necessary to have the Word preached at the Sacraments.--Dictu Magistri Knowles, Vicarii de Axminster, at that time present." Query, Can any of your readers say to what letter, and on what occasion such orders were issued by the archbishop, and also whether they have been published in any volume on ecclesiastical matters? H. T. E. _Margaret Burr._--It is related in Allan Cunningham's _Life of Gainsborough_, that he married a young lady named Margaret Burr, of Scottish extraction; and that "On an occasion of household festivity, when her husband was high in fame, she vindicated some little ostentation in her dress by whispering to her niece, now Mrs. Lane, 'I have some right to this, for you know, my love, I am a prince's daughter.'" The biographer of the _British Painters_ prefaces this by saying, "Nor must I omit to tell that rumour conferred other attractions (besides an annuity) upon her; she was said to be the natural daughter of one of our exiled princes, nor was she, when a wife and a mother, desirous of having this circumstance forgotten."
