My future grandchildren's names

I just came across a note in my purse from one of our trips to Bear Lake this summer. The kids were in the back of the van talking about what they wanted to name their children. I quickly grabbed my notebook and wrote down the names they came up with for posterity's sake. Here are the names of my future grandchildren:
Katrina chose the name Jacob. (She has 3 cousins named Jacob.)
Christopher will name his son Bobby Joe and his daughter Phoebe.
Caleb likes the names Jack and Christina. Hey, isn't that a juxtaposition of his two sibling's names! (Christopher + Katrina =Christina)
Won't it be fun to look back at this post someday when they are grown and starting their own families.
