Just looking of info on "Boondock Saints"

[Javakoala]

I know the scene of the twins talking to their mother was cut out, but it is on the DVD.  Who the heck plays their mom?  It looks like Eileen Brennan, but I can't find any confirmation on imdb.com.

Any help would be great.  And I apologize if this has been brought up before, but I wasn't able to access anything readily when I searched the site.
