Florence was Everett's second wife. They married on May 9, 1939. She was 23 and Everett was 42.  There's a photo of the wedding in BING magazine #144. This was what Carolyn Schneider wrote about her uncle Everett in BING magazine #144:
"Uncle Ev was devoted to Florence, his second wife. So much so, that in an effort to boost her operatic career goals, he arranged a European singing tour for her. Uncle Larry was appalled to learn that the gowns Ev told his wife to buy for the trip cost more than what Florence was being paid for her appearances. Definitely not one of Ev’s money making deals, no one had the courage to tell Bing. And it was a good thing too that uncle Bing wasn’t around the day Florence came in the Crosby offices and brought her pet monkey. She parked him right next to poor Magee who was trying to juggle a multitude of phone calls and had no time for monkeyshines."
