You may be surprised about how many such societies exist. One might expect states, counties and large cities to have historical societies. However, small towns may have them as well. For example, there are at least ten such organizations just in the northern part of San Luis Obispo County, CA. Nine of them are sponsoring a treasure hunt this month. Check out what is available where you live and also in any communities in which your ancestors lived. You never know what tidbit/treasure you may find about your ancestors until you look!
