A vintage ice cream parlour run by the Furellis.

Am I missing an apostrophe in Furellis? i.e. Furelli's?

Thanks,
Lorraine

No, Lorraine. It's a plural. One Furelli, two or more Furellis. (Course, only in English, not Italian!)

Thanks Jem.

Or, of course, just to confuse things

A vintage ice cream parlour run by the Furellis' aged mother-in-law...

The fortunes of the family owed in large part to Algernon Furelli's innovation when he modified the family ice-cream van to play Beethoven, achieving almost overnight market recognition for his slogan;

"Hear the Für Elise? Hear comes Furellis!"
