Can T Find My 5xgreatgrandfather Edward Braddock Born 1738 Chesterfield County All I Get is Information About General Edward Braddock

Six generations of Braddocks have lived in the same area. The flow of information just stops with Edward Braddock, supposedly born in Chesterfield (Cheraws District at that time)in 1738. I'm trying to find the point of entry into the US.
