Francis Locke Sr.
Francis Locke was born in 1722 in Ireland. He was the son of John and Elizabeth Locke. When he was still young, the family emigrated to Lancaster, Pennsylvania Colony, where Locke grew up. After his father died in 1744, his mother married John Brandon, who eventually moved the family to Anson County, North Carolina Colony. That area of the county was later split off as Rowan County, North Carolina.
Dowsing
In 1691 the philosopher John Locke, who was born in the West Country, used the term deusing-rod for the old Latin name virgula divina
. So, dowse is synonymous with strike, hence the phrases: to dowse/strike a light, to dowse/strike a sail.
