Note. The lord Montague. The person intended by this designation was sir Edward Montague, who was lord chief justice of the common pleas, as sir Roger Cholmley was of the king's bench. The new queen appointed sir Richard Morgan and sir Thomas Bromley in their places.

Before 10 Feb 1557 Edward Montagu (age 72) bought the manor of Boughton, Northamptonshire.

Note. P. 128. Funeral of sir Edward Montagu. The progenitor of the dukes of Montagu and Manchester, and earls of Halifax. He was buried at Weekley in Northamptonshire, where is his effigy, and the epitaph will be found in Bridges's History of that county, vol. ii. p. 347; also in Collins's Peerage, 1779, vol. ii. p 83, together with his will and biographical notices; but his monument is there incorrectly placed at Hemington.

Pepy's Diary. 22 Sep 1665. Among other discourse concerning long life, Sir J. Minnes (age 66) saying that his great-grandfather was alive in Edward the Vth's time; my Lord Sandwich (age 40) did tell us how few there have been of his family since King Harry the VIIIth; that is to say, the then Chiefe Justice, and his son the [his son] Lord Montagu, who was father to Sir Sidney¹, who was his father. And yet, what is more wonderfull, he did assure us from the mouth of my Lord Montagu (age 40) himself, that in King James's time ([when he] had a mind to get the King (age 35) to cut off the entayle of some land which was given in Harry the VIIIth's time to the family, with the remainder in the Crowne); he did answer the King (age 35) in showing how unlikely it was that ever it could revert to the Crown, but that it would be a present convenience to him; and did show that at that time there were 4,000 persons derived from the very body of the Chiefe Justice. It seems the number of daughters in the family having been very great, and they too had most of them many children, and grandchildren, and great-grandchildren. This he tells as a most known and certain truth.

Note 1. These are the words in the MS., and not "his son and the Lord Montagu", as in some former editions. Pepys seems to have written Lord Montagu by mistake for Sir Edward Montagu.
