_Colonel Thomas Walcot_ (Vol. vii., p. 382.) married Jane, the second daughter of James Purcel of Craugh, co. Limerick, and had by her six sons and two daughters: John, the eldest, who married Sarah Wright of Holt, in Denbighshire; Thomas, Ludlow, and Joseph, which last three died unmarried; Edward (who died an infant); William (of whom I have no present trace); Catherine and Bridget. The latter married, first, Mr. Cox of Waterford, and second, Robert Allen of Garranmore, co. Tipperary. John, the eldest son, administered to his father, and possessed himself of his estates and effects. I think his son was a John Minchin Walcot, who represented Askeaton in Parliament in 1751, died in London in 1753, and was buried in St. Margaret's churchyard. Two years after his death his eldest daughter married William Cecil Pery, of the line of Viscount Pery, and had by him Edmund Henry Pery, member of parliament for Limerick in 1786. A William Walcot was on the Irish establishment appointed a major in the 5th Regiment of Foot in 1769, but I cannot just now say whether, or how, he was related to Colonel Thomas Walcot. JOHN D'ALTON. Dublin. _Wood of the Cross: Mistletoe_ (Vol. vii., p. 437.).--Was S. S. S.'s farmer a native of an eastern county? If he came from any part where Scandinavian traditions may be supposed to have prevailed, there may be some connexion between the myth, that the mistletoe furnished the wood for the cross, and that which represents it as forming the arrow with which Hoedur, at the instigation of Lok, the spirit of evil, killed Baldyr. I have met with a tradition in German, that the aspen tree supplied the wood for the cross, and hence shuddered ever after at the recollection of its guilt. T. H. L. The tradition to which I have been always accustomed is, that the aspen was the tree of which the cross was formed, and that its tremulous and quivering motion proceeded from its consciousness of the awful use to which it had once been put. W. FRASER. Tor-Mohun. _Irish Office for Prisoners_ (Vol. vii, p 410.).--The best reference for _English_ readers is to Bishop Mant's edition of the Prayer-Book, in which this office is included. J. C. R. _Andries de Graeff: Portraits at Brickwall House_ (Vol. vii, p. 406.).--"Andries de Graeff. Obiit lxxiii., MDCLXXIV." Was this gentleman related to, or the father of, Regulus de Graef, a celebrated physician and anatomist, born in July, 1641, at Scomharen, a town in Holland, where his father was the first architect? Regulus de Graef married in 1672, and died in 1673, at the early age of thirty-two. He published several works, chiefly _De Organis Generationis_, &c. (See Hutchinson's _Biographia Medica_; and, for a complete list of his works, _Lindonius Renovatus_, p. 933.: Nuremberg, 1686, 4to.) S. S. S. Bath.
