You probably know Silas Merritt Robertson, better known as Uncle Si, as the tea-jug-toting, story-spinning breakout star of Duck Dynasty. He’s the guy who survived Vietnam with a plastic Tupperware cup and somehow turned "Hey!" into a national catchphrase. But while Si and his brother Phil became the face of a reality TV empire, they weren't exactly alone in that tiny house in Vivian, Louisiana.
Honestly, it’s kinda wild how many people think it was just the two of them. It wasn't. There were actually seven kids in total. Seven.
Growing up in the 1950s and 60s in rural Louisiana wasn't some Hallmark movie for the Si Robertson siblings. It was rugged. We’re talking no indoor plumbing, "hunt or go hungry" vibes, and a house that was basically held together by grit and faith. While the world focused on the bearded duo making millions from duck calls, the rest of the siblings were living lives that were, in many ways, just as interesting but far more private.
Who are the Si Robertson Siblings?
If you try to map out the family tree, it’s easy to get lost in a sea of "J" names and "Robertson" surnames. Basically, Si’s parents, James and Merritt Robertson, had a big crew. The lineup consists of five brothers and two sisters.
Here is the breakdown of the seven siblings:
- Jimmy Frank: The oldest.
- Harold: Another older brother who mostly stayed out of the limelight.
- Judy: One of the two sisters.
- Tommy: The middle-ground brother.
- Phil: The "Duck Commander" himself.
- Si: Our favorite storyteller.
- Jan: The baby of the family.
It’s worth noting that while Phil and Si became the public faces of the family, the others were far from slackers. In fact, a common piece of Robertson lore is that all of Si’s brothers and sisters actually graduated from college. Some even went on to get master's degrees. Compare that to Si, who famously dropped out of Louisiana Tech after three quarters before being drafted into the Army.

The Phil and Si Dynamic
You can't talk about Si Robertson siblings without focusing on the bond between Phil and Si. Phil is about two years older than Si, and they’ve been attached at the hip since they were kids. Back in high school at North Caddo, Si actually followed right in Phil’s footsteps on the football field. He even wore the same jersey number—number 10.
There’s this perception that Phil is the serious patriarch and Si is just the "crazy uncle," but their history is a lot deeper. When Si came back from Vietnam in 1993, he didn't just wander into a job. Phil brought him into the family business, Duck Commander, to make the reeds for the duck calls.
It was a perfect fit. Making reeds is tedious, meticulous work that requires sitting still for long periods. Si loved it because, in his own words, he got to "sit on his behind all day."
The Sisters: Judy and Jan
We don't hear much about Judy and Jan, and that’s likely how they want it. While the Robertson men were busy becoming cultural icons, the women in the family tended to keep things low-key.
Jan, being the youngest, has occasionally popped up in family discussions or podcast episodes. There’s a recurring theme in the family stories about how "mean" the Robertson kids were to each other growing up—not out of malice, but because that’s just how you survived a house with five boys. Si has joked about "hot-pepper torture" and various childhood pranks that would probably get parents in trouble today.

The "Other" Brothers: Jimmy Frank, Harold, and Tommy
Because Duck Dynasty focused so heavily on the West Monroe branch of the family, the older brothers—Jimmy Frank, Harold, and Tommy—remained largely a mystery to the general public.
They grew up during the "dark period" of the family's history. Before Phil found his faith and before the duck call business took off, the family struggled hard. James Harold (the dad) worked in the oil fields and was often away, leaving the kids to fend for themselves. This environment forged a specific type of toughness in all the Si Robertson siblings.
While they didn't join the reality show circuit, they remained part of the foundational support system that allowed Phil and Si to succeed. They were the ones who saw Phil at his lowest—dealing with alcohol and run-ins with the law—and stayed by him until he turned his life around.
The Secret Sister and Family Surprises
Just when people thought they knew everything about the Robertson family, a massive bombshell dropped in 2020. Phil revealed that he had an adult daughter named Phyllis from an affair he had in the 1970s, before he became a Christian.
While Phyllis isn't one of the original seven Si Robertson siblings he grew up with, the family embraced her immediately. It was a weird, full-circle moment for the clan. It proved that even with the cameras off, the Robertson family tree is still growing in ways nobody expected.

Sadly, the family has also faced significant loss. In May 2025, Phil Robertson passed away at the age of 79. It marked the end of an era for the siblings who grew up in that shack in Vivian. For Si, losing his "big brother" and lifelong partner-in-crime was a massive blow, but the extended family of siblings and nephews has remained remarkably tight-knit.
Why the Siblings Matter
Understanding the full scope of the Si Robertson siblings changes how you look at the show. It wasn't just a fluke of fame; it was a result of a very specific, very tough upbringing shared by seven kids who had nothing but each other.
The fact that they all managed to pull themselves out of poverty—most of them through education—is the real "American Dream" story that the TV cameras sometimes glossed over in favor of funny quips about squirrels.
If you want to dive deeper into the Robertson family history, your best bet isn't just rewatching old episodes. Look into the memoirs. Si’s book Si-cology 1 touches on some of these childhood dynamics, and Phil’s various books go into the "BC" (Before Christ) years where the siblings really had to lean on one another.
Next Steps for Fans:

- Look for the movie The Blind (2023), which actually depicts the younger years of Phil and Si and gives a visual of what their childhood home and sibling dynamic really looked like.
- Keep an eye on the "Duck Call Room" YouTube channel, where Si often gets sidetracked talking about his brothers and sisters.
The Robertson story didn't start in a boardroom or a TV studio; it started in the woods with seven kids trying to figure out how to make it to tomorrow.
