My mother's Welsh and I spent a lot of time there as a kid
My maternal grandfather's name was Powell - so I think I must have some Welsh somewhere in my background but most of my family line has been in Australia for 170 years plus, so it would be a long way back.
Most of my background is Protestant Scottish (lowland), Scots in Northern Ireland / bit of English and a sprinkle of Chinese .
