Oh my Dear Welsh friend.
It's the British. It's the British and the Europeans that owe the Compensation. It was your desire for Tea. For Tea and a little Sugar. Tea, Sugar, Silk and fine Porcelain.
"The main European nations involved in slaving were Portugal, Spain, Britain, France, the Netherlands, Denmark and Sweden. Britain began large-scale slaving through private trading companies in the 1640s. The London-based Royal African Company was the most important and from 1672 had a monopoly of the British trade. Other merchants who wanted to enter this lucrative trade opposed the monopoly and it was ended in 1698."

Now, because you're Welsh, and seem like a Good Fellow, I could probably find a way to strike YOUR name from the Compensation Fund List if you wanted, voluntarily of course, to send a 'Donation' to:
Postal Box General Delivery New Orleans ___ 'Attention Jack'.
