Palm Beach’s Rosalyn is obsessed with family, so how many kids and grandkids does she have?
She's the glammest grandma going
Palm Beach society on Members Only: Palm Beach is basically a glittery sport, the rules are strict, the guest lists are tighter, and everyone has opinions.
But while Rosalyn Yellin can absolutely spar with the best of them (and look fabulous doing it), the real through-line of her storyline is way less “who wore it first?” and way more “who’s coming over for dinner?”
Netflix describes Rosalyn as a passionate philanthropist and former dance fitness instructor who raised five children before moving to Palm Beach with her husband. And yes, the family details are just as big as her Palm Beach energy.

Rosalyn’s relationship with her husband, Jonathan Yellin, is very “grown, gorgeous, and grounded.”
While Members Only leans into the hierarchy of high society, think air kisses up front, power moves behind the scenes, Rosalyn’s marriage reads as her calm center.
Her hubby comes off as the supportive partner who’s there for the charity nights, the big moments, and the behind-the-scenes family life.
Even in cast coverage around the show, Jonathan is consistently framed as her longtime love and teammate.
He’s also described as a businessman, reportedly the CEO and founder of ABC Bail Bonds. The vibe is less reality TV “will they, won’t they” and more real-life “we’ve built a whole life together,” which honestly feels refreshing in a genre built on chaos.
And it tracks with Rosalyn’s overall brand on the show: she loves philanthropy, she loves tradition, she loves rules (at least the fashion ones), and she loves her people.
Netflix even positions her as a connector in Palm Beach, someone who advocates for causes and pulls others into the charitable social orbit.

So, we meet some of her brood on the show, but just how many kids and grandkids does Rosalyn Yellin have?!
According to Netflix’s official cast bio, Rosalyn raised five children before making the Palm Beach move she’d dreamed about with her husband.
As for grandkids, Rosalyn’s own Instagram bio spells it out. She’s a “Mom of 5” and has “4 grandbabies.”
We meet her eldest daughter during Members Only: Palm Beach episode three, Madi Yellin, as well as Madi’s other half, Jack, and their sons, Beau and Brooks.
Rosalyn is also mom to Mia, Mollie, Will, and Kyle.
That mix, five kids plus four grandbabies, explains so much about her energy.
Because when someone is juggling a packed Palm Beach calendar and a big family, you get that signature Rosalyn combo.
We’re talking glamorous, emotional, protective, and always a tiny bit ready to lecture someone for making a questionable choice… especially if it’s at a charity luncheon!
