Vyvyan House is pretty grand.
I imagine it was built for some branch of this Vyvyan family, but I'm only guessing. One of them was MP for Bristol, though...
Ah! Interestingly, the Clifton and Hotwells Character Appraisal says of neighbouring Vyvyan Terrace:
Vyvyan Terrace (1832 -1846) by Richard Shackleton Pope, was named after the Tory MP Sir Richard Vyvyan, who won the 1832 parliamentary election by defying the Reform Bill & bribing 1200 voters.
