I've got it!

I consider it my personal mission in life to figure out who babies look like. I pretty much nailed it with Ezra (he was a dead ringer for a young William Branham), and now I feel confident that I know who Luke looks like: Ron Howard. These photos make the resemblance pretty obvious. Discuss. (Sorry, I couldn't get a larger picture of this particular picture - its the one from the birth announcement.)
