Also of interest is the following note from the Complete Peerage vol 2 p264 sub Boyle of Kinalmeaky
"The four eldest [surv.] sons of the [1st] Earl
of Cork [by his 2nd w Catherine Fenton d 1643] are said to have been
popularly distinguished, as
(1) Richard the Rich afterwards 2nd Earl of Cork [I] cr. in 1664, Earl of Burlington;
(2) Lewis the Valiant (cr. in 1628, Viscount Boyle of Kinalmeaky [I];
(3) Roger the Wise, (cr. in 1628, Baron Boyle of Broghill [I], and in 1660, Earl of Orrery [I]; and
(4) Francis the Just, (cr. in 1660, Viscount Shannon [I]....
The only parallel cases are
(A) that of Sir William Bourchier, Count of Eu [by his w (her 3rd h) Anne [see note below] d of Thomas of Woodstock, Duke of Gloucester], all of whose sons, to the number of 4, were peers of the realm and sat together in ParI., i.e.
(I) Henry, Count of Eu, cr. Earl of Essex 1461,
(2) Thomas, Cardinal Bourchier, Archbishop of Canterbury,
(3) Sir William Bourchier, K.G., sum. to ParI. as Lord FitzWarine,
(4) Sir John Bourchier, K.G., sum. to ParI. as Lord Berners...
Note: Anne’s 2nd husband was the 5th Earl of Stafford by whom she had a son the 7th Earl of STAFFORD who was cr 1444 1st Duke of BUCKINGHAM, which brings to five the tally of sons who were members of the House of Lords.
(B) That of the 1st Earl of Mornington [I] [see above]
[C] That of Ralph Nevill, Earl of Westmorland [by his 2nd w (her 2nd h) Joan Beaufort d of John of Gaunt, see note below], no less than 13 of his relatives sitting together in the House of Lords from 1450 to 1455, i.e., 4 of his sons-in-law, 4 of his grandsons, and 5 of his sons, the latter being
(I) Richard, Earl of Salisbury,
(2) George, Lord Latimer,
(3) William, Lord Fauconberg,
(4) Edward, Lord Abergavenny,
(5) Robert, Bishop of
Durham.”
Note: Joan Beaufort's 1st h was the Baron Botelier of Wem and had two daus, co-heirs of their father.
Elizabeth (b ca 1720; d 29 June 1792) was eldest daughter of Henry Drax MP, of Ellerton Abbey, Yorks (b ca 1693; d 24 May 1755). She married firstly on 7 May 1744, Augustus Berkeley, 4th Earl of Berkeley, and had an elder son, Frederick Augustus Berkeley, 5th Earl of Berkeley. She married secondly on 2 January 1757, Robert Nugent, 1st Earl Nugent [I], by whom she had a daughter, Lady Mary Elizabeth, 1st Baroness Nugent [I], who subsequently married George Nugent-Temple-Grenville, 1st Marquess of Buckingham, and was thus mother of the 2nd Marquess of Buckingham and 2nd Baron Nugent (her second son by him inherited her peerage by special remainder).
