I wanted to add a few things:
Found out that June 8, 1947, Pauline played Sarah Palfey Cooke in a pro match held at the Beverly-Wilshire Hotel. Oddly enough the ref for this match was actor Walter Pidgeon. It was a fun event and they even played mixed doubles. Pauline played with Errol Flynn and Sarah played with Mickey Rooney. The ref was none other than Alice Marble. According to the LA Times, June 8, 1947 "It's likely that the eventual winner of the series will go on tour with Alice Marble..."
Alice would have been about 34-35 years old. A bit past her prime but still it's a shame it didn't happen.
Two other things. William du Pont Jr. is mentioned in the article Jeffster wrote. When I talked with Pauline she described him as "Boring and dull" Here's a picture of Will du Pont jr. I might add it's one of the best pictures I've seen of him. Normally he looks just like the banker he was.
I guess he wasn't Alice's cup of tea, but he did do a lot for tennis in the Delaware area. He married Margaret Osborne and apparently if you go visit their former estate some of Margaret's trophies are on display in the tropy room. Here's a picture of the Belleuve estate:
Pauline said that at times there were as many as 25 guests for dinner. A lot of tennis players stayed here. From Alice,Pauline, Louise and Margaret to male players such as William Talbert. I think Margaret Court in her bio also mentioned staying here. Poor Will no one wanted to sit next to him Pauline said.
