Hi Wildgoose
My mum's maiden name is Nicholls. Her grandfather Charlie could speak Romany; he worked at the brickfields near Sittingbourne, they had a site that the gypsies were allowed to use for a couple of weeks, and it was his job to move them on 'cos he could speak the language. He also had Romany symbols carved into his gateposts. According to a list on Romany Routes, Nicholls was a gypsy surname ... so the evidence is quite persuasive ...
