My situation was similar, but differed in that I had some aunts and uncles that left Catholicism; albeit, for some other form of Christianity. Mine was the first professed atheism. My maternal grandmother was about the same age as your Nan when I told her, we were also quite close. To my surprise she said she had always suspected. She lived almost another twenty years and our relationship only grew stronger. I can't say the same for others.
Be prepared for relationships to change, this isn't always bad. I fear in your situation that you'll eventually have to break silence on the matter as your boys grow. I'm not sure how I would handle the years of CCD leading to confirmation and the like. The religious education via CCD wouldn't be bad, but managing the indoctrination aspect while concealing your atheism with the entire family may become burdensome.
Good luck. I'll be here cheering you on.
