Major William Mayo (c. 1685 – October 20, 1744) was an English civil engineer who emigrated to the British colony of Virginia in 1723.
The New Creek, Mineral County area received its name from this Mayo expedition.
On the return trip, however, the explorers discovered the stream and subsequently placed it on the map as a "new creek."
Together with Professor Alexander Irvin, Mayo was also responsible for setting the boundary between Virginia and North Carolina.
[1] Mayo served as the chief civil engineer in Virginia until his death in Richmond in 1744.
