1934: Jury List Includes Four Women

The jury list back in 1934 for October included four women: Mrs. John Sather, Mrs. Otto Nordman, Mrs. E.E. Edwards and Mrs. H.C. Goodrich.

Were only married women allowed to serve, or was it simply a coincidence that all four women were married? (Of course, women did get married younger then, so there would be fewer eligible unmarried women purely based on age, one supposes.) And why were there so many men compared to the number of women?
