Willie Cubbon seems to assume that the smallest, 6s quarterland in the treen of Kyrkebryde is Ballabeg, (1515)
and shows McCowle in Ballabeg on his treen map. He has [Ffinlo] McCristen in Ballacowle. Looking at the earlier roll, there isn't a single, small quarterland.,There are two Q/L both of 10s 2d rent, both occupied by McCristens.
