There is nothing on the name in Caswell, but I have something for Pasquotank County, NC. If this record is yours, it is possible the person moved to other counties afterwards:

Pasquotank is in the far eastern portion of NC, while Caswell is in the central northern portion of the state. Wake County, the location of Raleigh is a about 3 counties southeast of Caswell. Here is a link to a map that might help you get the idea of the locations:
