I only know a few generations back and one line a few more generations. Of my great grandparents, one was born in Northern Ireland (with British not Irish heritage), one was born in NE England and the others were born in Scotland (one of of whom had Irish parents and two were from the Highlands). The line I know more about is Scottish and NE English and they worked mainly in the coal mining industry and some were part of a wealthy building industry, but I only know as far back as the early 1800s. Further back, there must have been some from the continent. My maiden name has Norman origins and my Mum's maiden name is German. On my Dad's side, there's talk of the family members from the Highlands having connections to Robert the Bruce and the surname suggests this is so, but I can't confirm it.
