Thanks again, Grampa, you have a great wealth of resources on your hard drive. And your soft drive.

When something historical comes up or a question like the Federalizing the National Guard, I use the best search machine on the internet. Yahoo.com and its search.
Yahoo.com's search is easier, faster and often more accurate than Google and the other searches. Below is the link to the Yahoo Search on "Federalizing the Nation Guard":
