The southern boundary was the glen leading to Inverkip; the West Burn flows down this valley, close to the line of the A78 trunk road.
The notes quote Crawfurd's 1782 History of the Shire of Renfrew referring to a walk-mill called "Elie-mill" as "lying within the barony of Gourock".
The mill site lies a short distance to the east of West Aughmead farm, on the location of the modern street named Aileymill Gardens.
The western portion of the Finnart estates was given by the king to Sir Archibald Stewart of Castlemilk, and subsequently became the barony of Finnart-Stewart,[7] which had its seat at Gourock castle.
Finnart rose to a powerful place as head of the Hamilton family, and was appointed to a series of high positions by King James V of Scotland.
