It is indeed Roxburrough, pronunciation wise that is. The name is derived from the erstwhile Scottish city Roxburgh (same pronunciation like Edinburgh, so burrough, shortened to b'rough, sounds a bit like bra). This city was founded about 500 years ago by the Scottish king and its time it was a prosperous commercant hub! But alas, only the proud bearers of the Roxburgh name, are our only memory to the beautiful city that once was... Roxburgh.
