England, Scotland, Wales, and Northern Ireland.

I can't speak for Lyle but it offends me. The mountains of KY had a large German immigant influx at one point. Wilhelm became William then Bill hence Hill Billy.

it is much more likely to have originated with the largely Scottish and Irish settlers. Scottish Hill folk and Billie or literally "bloke" or possibly the protestant followers of King William who came from Ulster in Northern Ireland. There is very little evidence suggesting it has anything to do with German Immigrants. Are you from Kentucky or are you just offended on behalf of White Americans?
