Little else is known of the poet Roull, though one poem by him may be extant. Stewart Conn, Edinburgh's first appointed Makar, has celebrated Roull's memory in his volume "Ghosts at Cockcrow". The title then fell to his eldest son John, who is believed to have been more of a soldier than a civil servant. In 1443 he was with the Earl of Douglas when he destroyed Barnton castle, a stronghold of the Crichtons. As a direct consequence Forrester's house at Corstorphine was razed. He died in 1454 and was buried in Corstorphine Kirk, where his tomb can still be seen. James Forrester of Corstorphine (son of the previously mentioned James Forrester), husband of Janet Lauder, was confirmed by Mary, Queen of Scots, on 5 February 1556 in the Barony of Corstorphine. In 1577 Sir James presented the parish kirk with a bell for its steeple. This bell still survives, although it was renewed in 1728. On 22 October 1599 Henry Forrester of Corstorphine sold various lands within the parishes of Corstorphine and St Cuthbert's. Henry died sometime around 1615 and his eldest son George became laird. James VI had already confirmed George Forrester, son and heir apparent of Henry Forrester of Corstorphine, and his wife Christine Livingstone in various properties in the barony of Corstorphine, on 15 November 1607. At Holyrood House on 30 July 1618 King James confirmed Sir George Forrester of Corstorphine in the lands and barony of Corstorphine. On 22 July 1633 he was created Lord Forrester of Corstorphine by Charles I. Lord Forrester had no sons, so resigned most of his properties, including Corstorphine, in favour of James Baillie. During the mid-17th century the family seems to have experienced some financial problems which resulted in lands being temporarily out of their control. On 3 August 1663 the lands and Barony of Corstorphine, except for the castle of Corstorphine and the town of Corstorphine, were granted to Sir John Gilmour. Oliver Cromwell had granted Laurence Scott of Bavelaw and his wife Katherine Binning, the lands, Lordship and Barony of Corstorphine, tower, manor-place, mills, mill-lands, parsonage etc., in lieu of the money due by James, Lord Forrester, to Beatrix Ramsay in Corstorphine who had assigned the debt to the said Laurence Scott, 1654.
