- Charles Beauclerk, Earl of Burford (b. 1692). Married in 1713 to his second cousin, Frederica Susanna Schomberg (and thus his issue descends from James I in three different ways, and from the Winter Queen in two different ways)

James FitzJames-DeVere (after his marriage in 1693), Duke of Berwick, Earl of Tinmouth and Baron Bosworth (b.1670). Married Lady Diana de Vere (b.1679) in 1693 (TTL the quarrel over the Colonel of The Blues position never takes place and James is in good enough standing to marry the daughter of the Earl).

Issue:
- James de Vere, Earl of Tinmouth (b.1696). Married to Lady Rachel Cavendish (b.1699) in 1716

(ATL) Anne Fitzroy (b.1691), married to James Berkeley, 3rd Earl of Berkeley, in 1711
(Note: instead of her cousin; marriage inspired by greater business contact between Grafton and Berkeley, vice-admiral of Britain, than between Grafton and Lennox)

Earls of Clarendon
Edward Hyde, Viscount Cornbury and 9th Baron Clifton (b.1691) (in OTL died in February 1713 of fever; TTL this first cousin once removed of Queen Anne survives). Married in 1713 Lady Louise Lennox (b.1694)

Earls of Essex
Algernon Capell, 2nd Earl of Essex (b.1670). Married
Lady Henrietta Butler, the youngest sister of 2nd Duke of Ormonde, in 1697
[The reason for this ATL marriage is that both OTL spouses of the Earl and Countess are unlikely to be in England TTL, having arrived in the retinue of William III OTL].

- Thomas Capel (b.1697), Viscount Malden.
- Algernon Capel (b.1700)
- Lady Elisabeth Capel (b.1702)
- Lady Henrietta Capel (b.1712)
