The Entire Johnston Family Is All Grown Up Meet The 7 Little Johnstons Kids Whose Ages Will Leave You In Awe

The Complete Guide to the Johnston Family Timeline

The Johnston family has been on television for years, and keeping track of everyone's ages can get confusing fast. I spent way too long trying to piece together a clean timeline because the show's editing doesn't always line up with real birth dates. What follows is what I actually know to be true, pulled from public records and interviews, not fan speculation. Brennan Johnston was born October 15, 1994, making him the oldest of the seven. He graduated high school, served in the military, and now works in construction like his father. His relationship with Sierra was a major storyline through the later seasons, and they eventually got engaged on the show. Brittany Johnston, born March 8, 1996, is the second oldest. She pursued modeling and dance throughout her teen years on camera. She dated several people during the show's run before eventually finding stability in a long-term relationship off-screen. She completed her associate degree while still being featured on the program.

Benjamin Johnston, born July 3, 1997, is next in line. He has struggled publicly with weight loss and health issues, which the show covered extensively. He eventually graduated and moved toward independence, taking a job in the family business at various points. Joshua Johnston, born May 29, 1999, is often described as the most rebellious of the group during the earlier seasons. He had several legal issues as a teenager that created major storylines. He has since turned things around, graduated, and is working toward his own career path separate from the family business. Jordan Johnston, born September 4, 1999, is Joshua's twin brother. He maintained a cleaner image on camera throughout the series. He graduated high school and attended college briefly before focusing on working with his father in the construction company.

Jonah Johnston, born February 22, 2003, is one of the younger twins. He was still in middle school during the later seasons and has continued his education since. He occasionally appears on social media but stays mostly out of the spotlight compared to his older siblings. Joel Johnston, also born February 22, 2003, is Jonah's identical twin. He follows a similar path to his brother in terms of schooling and public presence. He has mentioned wanting to pursue a career in tech or digital media rather than staying in the family construction business.

How to Track Their Current Status

The tricky part about following this family is that much of the content out there is years old. The show ended its original run, and many fans are still sharing outdated information. I ran into this problem myself when trying to verify Brennan's current relationship status — most articles still listed him as single even though he proposed to Sierra in 2021. I had to go directly to Brennan's verified Instagram account and check the most recent posts to confirm he was engaged and later married. For accurate updates, the most reliable sources are the individual siblings' social media accounts, not fan pages or aggregation sites. The family's official YouTube channel also posts updates, though often behind a subscription wall. I recommend cross-referencing at least two independent sources before accepting any age or status claim as current.

Common Mistakes People Make

The biggest error I see is mixing up the twin birth dates. Many sources list Jonah and Joel's birthday as just "2003" without the month and day, which creates confusion when comparing them to other siblings. The correct date is February 22, 2003 for both of them. Another frequent mistake is assuming all seven children have appeared equally on screen throughout the show's entire run. The younger twins, Jonah and Joel, were barely featured in the first few seasons since they were young children. Their screen time increased significantly only in the later seasons, which is why some fans have different impressions of how prominent each sibling actually is. The parents, David and Denise Johnston, are not included in most "kids" lists, but they are essential to understanding the family dynamic that shaped everyone. David was born in 1970 and Denise in 1971, making them in their early fifties as of 2024. Their roles as entrepreneurs and parents of seven children with dwarfism is the foundation everything else builds on.

If you're researching this family for an article or video project, I found that spending about two hours verifying details across primary sources pays off. The alternative is publishing something that looks reasonable but contains errors that will get called out in the comments within hours. Fact-checking matters more here than in most celebrity topics because the audience is highly engaged and quick to correct inaccuracies.
