This is the first of a three part series. Life is good for the family historian with dozens of records containing direct evidence. Accurate and complete marriage certificates that list the marriage date, full legal names, and the names of each set of parents can be more valuable than a shoe box full of money in the search for a missing ancestor.

The USGenWeb® Project was established in 1996 by a group of genealogists who shared a desire to create free online resources for genealogical research. Originally beginning with online directories of text-based resources, their vision has grown into a network of over 3000 linked websites, all individually created and maintained by a community of volunteers. Today you may find a variety of unique county and state resources including photos, maps, transcriptions, historical documents, helpful links, and much more.
