I've created an online version of the 1873 Titus Atlas. This is a list of all 6300+ names placed on a Google map to make it easier to find where your ancestors might have lived. You can search by surname, though there are generally only first initials.
This is only a general idea of where you might find your family's property. If you don't find your ancestor try a different spelling, though it's very possible that they are not in the atlas.
