While looking through some photos on my computer, I ran across this one of me the day I was born. It looked very similiar to one of the 4D ultrasounds. So I put them side-by-side to compare. Then I looked for a similiar photo of Jace and compared those. Unfortunately I don't have any newborn photos of Ben scanned, they are all stored away, so I couldn't add him to the comparison.

But this is what I came up with. Think we're related?
