One month after the death of Florence Henderson
, friends and family, including some of her former Brady Bunch
co-stars, gathered on Thursday to honor the iconic actress.
"Most beautiful evening with family and friends celebrating our beloved Florence," Maureen McCormick wrote on Twitter, along with a group photo.
A few of McCormick's Brady Bunch siblings, Christopher Knight, Susan Olsen and Mike Lookinland, as well as Happy Days star Marion Ross, were among those in attendance.
"What a cool woman Marion Ross is! Love her and her zest for life and her loving spirit!" McCormick wrote.
Last month, McCormick sat down with ET
and opened up about Henderson's impact on her life.
"She was an incredible example of how to live your life," McCormick told ET's Nancy O'Dell. "She was that sweet. She really was. She was the loveliest of ladies."
Henderson famously played matriarch Carol Brady for the five immensely popular seasons of The Brady Bunch (1969-1974), while McCormick played her eldest daughter, Marcia. McCormick recalled being 12 years old when she met Henderson, who left an indelible first impression.
"I was just like, 'Wow! She's so beautiful,'" McCormick fondly remembered. "That woman in no makeup was the most beautiful thing."
Away from The Brady Bunch set, McCormick spent "pretty much every weekend" at Henderson's house with her family. McCormick said they would "hang out in our pajamas all day" or "be in our bathing suits by the pool."
Despite their 22-year age difference, the two formed a strong bond that lasted up until Henderson's death.
"Florence played our mother on the show, but I always felt like she was more of a sister,” McCormick, 60, shared. “She was so young at heart, and just a really good friend."
