Career
He was also a Senator of the College of Justice with the title Lord Renton. Sasine was given on 29 November 1673 and recorded in the General Register on 7 January 1674. Lord Fountainhall stated that Sir John Home of Renton was advanced to his position by favour of the Duke of Lauderdale, although Lauderdale quarrelled with Renton in 1664, and when it was proposed that Renton be made Lord Chancellor of Scotland the Duke remarked that "Renton had not the fortune able to bear out the rank of a Chancellor".
Fountainhall says Renton was "a most premptor man to his inferiors or equalls, but a slavish fearer of any whom he supposed to be great at Court, on whom he most obsequiosly fauned." Lord Renton married (1) (contract dated 15 February 1622) Janet, daughter of Sir George Home of Manderston.
