"Slave ownership, it appears, was far more common than has previously been presumed. Many of these middle-class slave owners had just a few slaves, possessed no land in the Caribbean and rented their slaves out to landowners, in work gangs.These bit-players were home county vicars, iron manufacturers from the Midlands and lots and lots of widows. About 40% of the slave owners living in the colonies were women. Then, as now, women tended to outlive their husbands and simply inherited human property through their partners wills".the Observer, History of British Slavery
