The President’s ancestry is 50% Scottish and 50% German. No English.
Mother’s side: Scottish
Father’s side: German - from Bavaria and Hesse
Scotland is British, and Trump’s mother was a staunch royalist, as he was keen to point out when he visited Britain not so long ago.
So we have a half-British president leading the US and an American born Prime Minister leading the UK. A pretty good time for UK-US relations given the links both leaders have with the other nation.
