i added you so you can see his bio. but basically their mother came from one of the five families in nyc. married their father who was working his way up through the ranks at the time. they were sent to boston. boston is leone territory for the most part. nico has a legitimate nightclub but also runs certain aspects of the organized crime biz. he's the older with two younger sisters. they're all very close-knit, always in each other's business, nosy af, etc. the girls have always been pretty sheltered. neither nico nor his father ever shares details with them. their mom and dad are very close though and mom knows more than she'll ever let on. still very much in love, etc etc. i always imagined the girls know exactly what the family is/does but probably went their own way for the most part, as far as work and such.
