He built a house in this gap.

by Lisa Y. Henderson

Footnote 41. Ambrose Gap is a few miles southwest [of Cut Laurel gap], and is so called because a free negro of that name built a house across the State line in this gap, and when he died his grave was dug half in Tennessee and half in North Carolina, according to local tradition.
