There were probably more Irish slaves sent to the West Indies than Irish slave traders - but there were some of the latter. And at least one, Richard Brew would count as notorious.

But I repeat - when we are talking about history, it is never a matter of "us", it's always a matter of "them". Whether we are talking praise or blame, heroes or villains, slave owners or slaves. We can't shoulder any guilt, and we can't lay claim to any praise.
