Brenda Lee Marquez McCool, 49
McCool was a mother of 11 originally from Brooklyn, New York, according to a GoFundMe page set up by one of her sons.
She was at Pulse with her son and niece, both of whom survived, according to The Advocate.
She had battled cancer twice, her son said on the GoFundMe page. He called her a "wonderful and caring woman." McCool posted a video
from inside Pulse just two hours before the shooting. "She was a fighter. A cancer survivor. A stellar mother. A proud and fierce advocate for her LGBT family," Wilson Cruz wrote in a tribute to her on Facebook.
"She spoke passionately about how much she loved her children. She was hilarious and loving and tore up the dance floor when salsa or anything was playing. I can't believe she's gone. I mourn with her kids and my entire family. The violence and hate has to end. The guns have to f*cking GO! Our hearts are BROKEN!" (Facebook)
