Nope!
Black slaves got Irish names from... Irish slaves.
People may have heard how the Irish experienced a ton of prejudice. It lives on today - Ever heard of "kick a ginger" day or someone making fun of a person's hair color? We should all be aware that the British basically hated the Irish. The great potato famine? There was enough food being grown, but the British wanted it all and didn't leave much for the Irish themselves.
The Irish slave trade began when James II sold 30,000 Irish prisoners as slaves to the New World. His Proclamation of 1625 required Irish political prisoners be sent overseas and sold to English settlers in the West Indies. By the mid 1600s, the Irish were the main slaves sold to Antigua and Montserrat. At that time, 70% of the total population of Montserrat were Irish slaves. Ireland quickly became the biggest source of human livestock for English merchants. The majority of the early slaves to the New World were actually white.
From 1641 to 1652, over 500,000 Irish were killed by the English and another 300,000 were sold as slaves. Ireland’s population fell from about 1,500,000 to 600,000 in one single decade. Families were ripped apart as the British did not allow Irish dads to take their wives and children with them across the Atlantic. This led to a helpless population of homeless women and children. Britain’s solution was to auction them off as well.
African slaves were very expensive during the late 1600s (50 Sterling). Irish slaves came cheap (no more than 5 Sterling). If a planter whipped or branded or beat an Irish slave to death, it was never a crime. A death was a monetary setback, but far cheaper than killing a more expensive African.
The English masters quickly began breeding the Irish women for both their own personal pleasure and for greater profit. Children of slaves were themselves slaves, which increased the size of the master’s free workforce. Even if an Irish woman somehow obtained her freedom, her kids would remain slaves of her master. Thus, Irish moms, even with this new found emancipation, would seldom abandon their kids and would remain in servitude.
In time, the English thought of a better way to use these women (in many cases, girls as young as 12) to increase their market share: The settlers began to breed Irish women and girls with African men to produce slaves with a distinct complexion. These new “mulatto” slaves brought a higher price than Irish livestock and, likewise, enabled the settlers to save money rather than purchase new African slaves.
This practice of interbreeding Irish females with African men went on for several decades and was so widespread that, in 1681, legislation was passed “forbidding the practice of mating Irish slave women to African slave men for the purpose of producing slaves for sale.” In short, it was stopped only because it interfered with the profits of a large slave transport company.
On a related note... There was a point in time when both white and black (and mulatto) slaves were clamoring for freedom. It was difficult to track down a white slave (they blended in easily) and white people started to see white slaves as "one of them". The slave owners eventually freed the white slaves. They started to invite the white slaves over to their mansions as guests. They would say, "This could be you, some day! Just stay away from those dirty Negoes!" And thus the white former-slaves started to feel distant from the still-enslaved blacks. They now felt better than them. Now, few white slaves remained and thus the white population no longer felt as much empathy - They could now separate themselves from this whole slave business. It was a negro problem.
This sort of culture is still visible in the south, where equally "ghetto" (redneck) whites will still claim to be superior from the blacks, regardless of the fact that they're basically in the same boat. Those rednecks are not the descendants of the plantation owners; they moved on to business ownership, factories, and into leadership positions. That evil 1% we complain about these days? Those are the plantation owners of the past.
