There is a certain demographic that has occupied the lowest strata in American society since the Colonial Era. They were first brought here as convicts when America was utilized as a penal colony, laborers being in short supply here and the lowest of the criminal class being unwanted there, well, you do the math.
To this day, this subset remains the least educated, highest unemployed, and the most prone to violent criminal behavior in the USA. Settled mainly in Appalachia and oft found in trailer parks and other less desirable living areas throughout America as well today, their genealogy can all be traced directly back those specific British roots.
