These books are easy to read, contain good definitions and explanations of genealogical jargon, and have many sample charts. In terms of computer programs for genealogy, I have always used Family Tree Maker by Broderbund. It has been very easy to use and contains good help menus. Each new version has improved its user-friendliness. I am new to the Internet and have barely begun to tap into resources available there.
Much information is available with more added every day.
The most important thing about genealogy is to have fun delving into your past. I have discovered many surprising things about my family, debunking a few of those old family stories, but finding new, entertaining, and factually based stories to replace the old. As you search for your Civil War ancestors, you may discover that genealogy is as much fun and addictive to you as it is to me.
