Answer:
Technically, yes.
Explanation:
Until the end of the Civil War, it was common for slave owners to rip families apart by selling the children or the parents to other slave owners. If you really think about it, it's very possible that many slaves were given new names by their owners. There was not much consideration for slaves' feelings or cultural attachment. Many slave also underwent changes of names/surnames after emancipation. (Gosh.. this subject is so sad. Anyways, I hope this helped a little.)
