I've been encountering a lot of fictional people called Sowerby lately. The Sowerby family - Martha, Dickon, and their unnamed mother and ten siblings - play a large role in The Secret Garden. Farther south, Mrs Sowerby is one of a number of characters living in Stockbridge played by Susan Brown in Plague of the Daleks the latest Big Finish audio in their main Doctor Who series. And farther south again, I'm also reading Trollope's Framley Parsonage, where there is a villainous Sowerby who I hope will come to a sticky end.
I don't think I've ever met anyone of that name in real life.
