Stuck in the middle

So the other night, while trying to fall asleep after a middle-of-the-night feeding, it suddenly dawned on me that I have yet to explain the big "surprise" - Jack's middle name. Although a number of people guessed Jack's middle name before he was born, we were able to keep the news from the one person we didn't want to find out, Jon's Grandpa Lawrence "Larry" Tillman.
Although both of Jon's sisters have children, Jack is the first grandchild and great-granchild to bear the Tillman last name. He's also the fifth generation of Tillman men here in the United States. So when looking for a name, Jon wanted to research the Tillman archives. Some of our options were great-great-great-grandpa Frederick "Fritz", or great-great-grandpa Derastus (my personal favorite), or great-grandpa Samuel. We settled on Lawrence, not only does it sound great with Jack, but it is also the one Grandpa Tillman that Jack will have the opportunity to meet. Here is a picture of Jon and his grandpa Larry.
