Paul was not religious, but I'm sure that they will still have some sort of Chanukah celebration, even if it is small. When we talked about God and having faith, he often told me that he wished he could feel something, but just didn't. Still, he would participate in the annual Seder, etc., so I'm sure that his family will be doing something, but I'm sure it will be difficult. Faith or not, this time of year is always hard when you've suffered such a loss.
