Lauren Hope Caldwell was born on May 22, 2000, in Fairfax, Virginia, to Paul Caldwell and Christina Caldwell. She was the couple's second child, and they went on to have seven more children after her.
Along with her siblings, Lauren was homeschooled growing up. She finished in 2018. In July 2019, when Lauren was 19 years old, her family shared that they had recently celebrated her high school graduation at a party at the Duggar house on July 14, 2019. The hashtag #betterLateThanNever suggests that the party took place "late" compared to when she completed her schooling.
As a young child, Lauren and her family lived in Woodbridge, Virginia, where her father was a Pastor at Heritage Baptist Church. In 2008, her father was sent by Baptist International Missions, Inc. to plant a church in Fayetteville, Arkansas. She has lived there with her family since then.
On October 15, 2020, Lauren's parents announced that Lauren got engaged to Titus Hall. They got engaged on October 8, 2020 at Panama City Beach in Lower Grand Lagoon, Florida. It is unknown how they met or when the two of them started courting. At some point, the couple quietly ended their engagement. On December 2, 2020, the Caldwells and the Halls erased the engagement announcement from their social media accounts. They have made no statements. Since then, Lauren was spotted in Duggar family YouTube videos not wearing her engagement ring. On December 26, 2021, their relationship was officially confirmed to be over when Titus's mother announced his engagement to another girl.
