“ In 1638 Lennox was appointed keeper of Richmond Park, and in 1640 warden of the Cinque ports. On 8 Aug. 1641 he was created Duke of Richmond, with a specific remainder, failing heirs male of his body, to his younger brother. Shortly afterwards he accompanied the king to Scotland, but, not having at first signed the covenant, was not permitted to take his place in parliament (Balfour, Annals, iii. 44) until the 19th, when he subscribed ‘the covenant band and oath’ (iii. 46) . ”
