Looking at Woods Atlas, Thomas W. Corlett owned 4 main areas of land (marked 56t). These are at (roughly) OS Grid refs:
Carmodal Beg SC 354 924 (north of St. Mary's Glen)
A piece of land to the west of the glen road, south of The Gliack SC 350 926
One quarter part of a rougly circular 'intack' in the Curragh SC 365 945 (north of the Wild Life Park)
A field just Ballaugh side of the Wild Life Park in the Ballavolley area SC 941365

Farms in those days were often as fragmented as they are today! Hope this helps.
