There may indeed be some other articles which open with the formula '(First name) (middle names) "(nickname)" (surname)' but it is always ugly writing and WP:OTHERSTUFFEXISTS applies to fields wider than deletion debates. I tend to leave alone non-British, especially American, articles where usage of names is different but there really is no excuse in a British context for it. Meanwhile, you ask for evidence of absence which poses a well-known philosophical problem which as a philosopher of science I would turn round to say that my hypothesis is easily falsifiable. Did anyone ever say, e.g., "What do you want for your dinner, Georgette Lizette 'Googie' Withers?"
