This just in: the baby has a name!
Benjamin and Daniel are the names of my brother's and sister-in-law's respective fathers. As for Ikey, I can't really explain that. He was frequently referred to as Ikey in utero, but where that name came from I couldn't say. In any event, naming a child one thing and calling it something entirely different is something of a family tradition (viz., Mary Elizabeth is Libby and Margaret Elaine is Molly). Also, one of their cats is also named Benjamin.
