Nanny Roos is a good guess!  Unfortunately a wrong one too.

I think she won him once.

These are US State Championships in which women won overall.  Menchik wasn't American.

2 out of 2.  Impressive!

"Chess Life" Sept. 20, 1956  by Willa Owens.
“Hurray for Irene Vines!  Our giant killer won the Louisiana State Championship in a very strong field of 47 players. 
Mrs. Vines was the only undefeated player in the first five rounds.   Her last round opponent was Mr. R. S. Scrivener, Memphis, Tennessee city champion, whose score was 4.5.  Drawing her 6th round game gave Mrs. Vines a clear win of the Open Tournament as well as the state championship.  This is probably one of the strongest mixed tournaments ever to have been won by a woman in the United States, though it is not the first time a woman has been state champion.  Mrs. Adelle Belcher
was State Champion of Vermont.

Scrivener, by the way, was a very strong Memphis player.

Thanks for playing!

Thank you, batgirl! I had a lot of fun looking up all the great women's players from the mid-20th century. I think it would really interesting to continue gathering information on these forgotten players. And thanks for the articles as well

Well, here's a list of my articles on women players, many from America, some from around the world, many forgotten, most unappreciated: http://www.chess.com/blog/batgirl/about-women-and-chess

Vera was in a class by herself.

Crude.

It's the thought that counts....
