A friend just gave me this book to borrow because she really liked it and the woman has a brother with Ds who is her "sidekick." I haven't read it but if you all decide to it'll probably give me a boost

It's called:

She's All Eyes:Memoirs of and Irish-American Daughter by Maura Conlon-McIvor

Here's what i found on Amazon

From Booklist
Growing up Catholic in the 1960s, Conlon-McIvor's favorite religious figure was the Blessed Virgin Mary, and her favorite book character was Nancy Drew. Mysteries fascinated her, and no wonder; her father was an FBI agent, whose car trunk was filled with bullets. Her dream was to follow his path and crack "the code" that made his every glance and word so deliciously baffling. It took many years before Conlon-McIvor understood that her father's taciturn, moody behavior had little to do with his job; it grew from deep sadness and an inability to express emotion. In this touchingly honest memoir, always true to a child's point of view, the author remakes herself as the naive child and awkward teen she was, growing up in a family mostly held together by commitment to her youngest brother, born with Down syndrome. Memories of her long-suffering mother; her beloved uncle Father Jack; and, most of all, her father, whose "code" she finally cracks, blend beautifully in this occasionally funny, affecting account of family ties and personal growth.
