Records of the Isle of Man Rolls Office: Tithe Commutation Plans This series consists of 2939 individually hand drawn plans showing land held by landowners on the Isle of Man, circa 1840. The plans were originally lodged with the Isle of Man Rolls Office under The Tithe Commutation Act 1839. The plans are bound into a series of large volumes and are organised by parish. Some parishes extend over more than one volume. The date that the plans were bound is not known, but it appears plans were pasted onto paper or linen before binding. Any plan larger than the volume was folded, sometimes several times and in several directions, to fit. Plans are numbered sequentially within each parish volume. The plans come in a wide variety of shapes and sizes, from 2 inch square to over 2 foot by 4 foot. Some are highly decorated and hand-coloured, while others are very rudimentary. circa [1840]
