Surnames SMELLIE, CRAPP, TROLLOPE and PRATT.....
No, I'm not being rude; these are surnames which I've come across in my lifetime.
A lady (quite a posh one) that my mum knew whose surname was Smellie. A girl I was at school with in the 70s whose surname was Crapp (she was not a happy bunny). Another girl in the year below me whose surname was Trollope - her parents made sure she was doubly burdened by giving her the christian name of Griselda; and Pratt, the name of a certain Sid who used to board at my grandma's house - always the butt of family jokes...

Obviously, these names have an origin...

but thankfully, I've personally avoided them!
