Some mixed-race people in the South became wealthy enough to become slave owners themselves. At times they held family members in slavery when there were many restrictions against freeing slaves. By the time of the Civil War, many mixed-race persons, or free people of color, who were accepted in the society supported the Confederacy. For example, William Ellison owned 60 slaves. Andrew Durnford of New Orleans, which had a large population of free people of color, mostly of French descent and Catholic culture, was listed in the census as owning 77 slaves. In Louisiana free people of color constituted a third class between white colonists and the mass of slaves.
