JOHN STUART FIRST MARQUIS OF BUTE In 1766, John Stuart, 1st Marquess of Bute married into the Herbert family and was later created Baron Cardiff. In 1778, he began renovations on Cardiff Castle. In the 1790s, a race track, printing press, bank and coffee room all opened, and Cardiff gained a stagecoach service to London. Despite these improvements, Cardiff's position in the Welsh urban hierarchy had declined over the 18th century. Iolo Morganwg called it "an obscure and inconsiderable place", and the 1801 census found the population to be only 1,870, making Cardiff only the twenty-fifth largest town in Wales, well behind Merthyr Tydfil and Swansea. source .. https://en.wikipedia.org/wiki/History_of_Cardiff
