I can add some information in this area.I'm not sure what brought them to Pawtucket but the 1905 Rhode Island Census can give us an idea when.
It appears Napoleon was first in 1885, Philibert in 1888, Joachim and Joseph in 1889, and "Almedos" in 1895. All of them were carpenters and lived near each other.Napoleon lived the furthest at seven-tenths of a mile as approximated by Google maps. There are some naturalization cards online to support these years too.
I also have their father passed away in Rhode Island August 24, 1889 and my current assumption is Pawtucket.
