In Sicilywas their not more of these people under the kingdom of Naples from 16th century onwards ?
I have seen numbers of 40000 plus
" La loro consistenza numerica andava da circa 7.500 unità originarie a 8.234 nel 1570 ed a 8.958 nel 1589. E questo quando la popolazione complessiva dell'isola non arrivava in quegli anni alle 800.000 unita."
The 7,500 WAS given in 1550.
In 1542 Southern Mainland Italy: 5775 people.
So in 1550 there were around 13,000-14,000.
Their population did grew over 40,000 within time of course.
Some other waves came in next centuries.
