During the recent Supreme Court arguments over grandparents’ visitation rights in Troxel v. Granville, much was made of the fact that six of the nine justices are grandparents.

Next month, coincidentally, we’ll be hearing a lot more about one of those black-robed grandparents, namely Justice Sandra Day O’Connor. Courtney O’Connor, the 10-year-old girl whose birth made Justice Sandra Day O’Connor the first grandmother ever to sit on the Court, is set to appear on the “Today Show” and elsewhere to promote a new children’s book, “Meet My Grandmother: She’s a Supreme Court Justice.”
