The Kinards should be flattered to have Black family members. After the Civil War when the slaves were freed, they were told they had to have a surname and they could choose. Many took the name of their owners, many took a name of people they genuinely liked who had been kind to them. It is also possible there are Kinard marriages with former slaves in SC and AL and MS where they primarily lived before the Civil War, as the Black population was very large in those states.
These Kinards originate from Germany in the Newberry Dist. of SC, they are cousins in Germany of the huge Koiner, Coiner, Coyner family from Germany and PA and VA. As are the Kinards, Keinards, Keinarts of PA. The name is Keinadt in early history, Keinath in Germany today. Norma
