Believe it or not, English....from Kent. Means Valley of the OX. I dunno.
Oxendine is a common name in Scotland county as well as Robeson county, North Carolina. My youngest brother used to do construction work in the area and he used to refer to the LOF (Libby, Owens, Ford) plant as “Locklear, Oxendine and Friends” because most of the employees there were said to be named either Locklear or Oxendine.”
I have been under the impression that Oxendine came from Scotland but maybe it is English. Most Oxendines are more than sixty percent “native American”, specifically Lumbee indian.
