I've shamelessly pinched this idea from the lovely Sally Quilford - mainly as a distraction from the editing pit, and also as a nod to the upcoming royal nuptials.
"What's your royal wedding guest name? Start with either Lord or Lady. Your first name is one of your grandparents names. Your surname is the name of your first pet - double barrelled with the name of the street you grew up on."
Mine would be Lady Ethel Bomber-Coniston. Which is plain ridiculous. Bomber was a budgie by the way. Not a fashionable pet these days.
I think you get the drift.
