OK, I have finally posted the true story behind the Sons of Katie Elder in the Katie Elder area. It's long, but it's a very complex story. I'd recommend reading the referenced publications for the whole story. If anyone here will be at the Wild West History Association convention in Cody, Wyoming at the end of the month, I'll be there, too. Look me up.

Many thanks Jim, I sure wish I was in a position to be able to look you up!
