Unity is said to have received its name after the younger of two brothers asked the elder to lend him £1,000 to buy this plot of land; the elder brother refused to do so and the relationship beten them became strained. However, both went to church on the following Sunday. The text for the sermon was taken from a psalm which reads in part: "Behold how good and pleasant a thing it is for brethren to dwell together in unity".
Unity was purchased by John Tharp in
1778 and the Jamaica Almanac of 1840 lists Edmund Francis Green as
owning1863acres at Unity
The Estate is now a land settlement area.
