Ozma is the ruler of the Land of Oz, beginning with the second book in the Oz series, "The Land of Oz" by L. Frank Baum. Most people these days are only aware of the first book, "The Wizard of Oz", but there were forty more "official" books and a lot more unofficial ones after that -- also, several movies and stage plays.
When I first went online I needed a username for e-mail, and at the time I was reading the Oz books to my younger daughter, Jillian -- she chose Ozma for my user name. Neither of us gave any thought to it someday becoming my common internet username, or we might have picked a male character! As for the number, my volunteer fire department is base 90, and I'm firefighter #14 -- in other words, 914. And so, I've been Ozma914 ever since. Here's a John R. Neill drawing of Ozma, who according to Baum was far and away and most beautiful person, inside and out, in all the land:
On an unrelated note, I'm back online. I lost my voice to a bad sore throat/cold, and then took an unplanned trip to Missouri to pick up Emily, so I've been away for about four days. In addition to her two weeks without power due to the ice storm, Emily's been going through a lot of other stresses down there and needed some time away, so I brought her back up here for awhile -- at least until the end of summer, I'm hoping. We've already embarked on a reorganizing plan for my home office and book collection, and with any luck we'll both be spending our free time working on our fiction writing careers once she's settled in.
