Jessa and her husband, Ben Seewald, welcomed little Henry Wilberforce in February, and revealed a few weeks later the meaning behind his unique moniker.
"William Wilberforce was a British politician in the 1700s ... he was instrumental in abolishing the slave trade," Ben said of Henry's middle name in a video posted to TLC's website. "He's a real hero of ours. Someone that really walked with God."
As for his first name, Ben admitted there was a far simpler reason: "Jess really liked the name Henry, and we just thought it was cute."
