"_Salusbury Welsh Pedigree Book._"--Having sometimes occasion to investigate the lineage of Irish families derived from Wales, I am very anxious to learn, through your valuable oracle, where may now be that genealogical collection. According to the notes I have of it, it contained "the pedigrees of all the gentlemen in North Wales, and of some adjacent counties, with their arms finely illuminated;" and took its name from the compiler, John Salusbury, Esq., of Erbistock, who lived about the middle of the seventeenth century, and is reported as having executed the labour with great accuracy. Does its actual scope justify the above description, and where is it now? About the year 1780 it was in the possession of Sir Watkin Williams Wynn, the very surname on which I am at present engaged. JOHN DALTON. 48. Summer Hill, Dublin. [In all probability, the present Sir W. W. Wynn could give some information upon the subject if applied to.] _The Earl of Erroll._--I have somewhere seen it stated, that in virtue of his distinguished office as Great Constable of Scotland, which was granted to his ancestry by King Robert Bruce, in 1312, his lordship is by birth the first subject in Scotland; and in right of this privilege, on all state occasions, where the sovereign is present, appears at his or her right hand, and takes precedence of the entire peerage of Scotland. Is it so? PETROPROMONTORIENSIS. [His Lordship cannot be by _birth_ entitled to precede the whole peerage of Scotland, though as Lord High Constable, when attending the sovereign, he may have that precedence.] _Heraldic._--A friend has sent me the following Note "from a local paper:" "In the hall, Fawsley, Northamptonshire, is an escutcheon, containing no less than 334 quarterings." Can any of your correspondents verify this statement, or refer me to any other example of so full a blazonry? W. SPARROW SIMPSON, B.A. [The shield is probably that of _Knightley_, whose quarterings are very numerous. We do not know where to refer our querist to an emblazoned shield, but there are other families whose quarterings would be as numerous, viz. _Howard Percy_, and Brydges Chandos, Duke of Buckingham, &c.] _Family of Grey._--Thomas, second Marquess of Dorset, had four sons; Henry, Thomas, Leonard, and John. Henry was created Duke of Suffolk, and was with his two brothers, Thomas and Leonard, beheaded in 1555, for taking part in Sir Thomas Wyatt's rebellion. John was ancestor of the Earl of Stamford. The Queries I wish to make are, were Thomas and Leonard, or either of them, married? If they were, what were the _names_ of their wives, and did they leave issue? And most particularly did Thomas? C.
