Hi radriano, if she's going to BU she'll be right down the street from Boston College where they have an Irish Studies program directed by (still is ?) fiddler Seamus Connelly. There they would know about most schools in the area (Seamus's ex was quite the teacher). The local Comhaltas chapter would be a source of good infomation. The Boston Globe has in it's calender section (every Thursday)a dance listing as well a great folk music listing. That would be another source. Good luck & nice to say HI to you again. If not let me know & I'll dig deeper.
