Have you been to a library to conduct your genealogy search? Please understand that the majority of stuff related to our families is offline. Books though are becoming a more popular item to be scanned in full and put on the internet.
When completing your research the local libraries where are families live often has some very unique resources that you will only find in that library. A common one is family histories. As genealogist complete their research and their families live in a specific area the finished genealogy will be given as a gift to the library. Many of my own family lines have genealogies that could find no where else than the local library where they lived. A variety of other records will also be at the library that have yet to be on the Internet. Take a look at the resources at the local libraries where your ancestors lived and plan a visit or hire a local researcher.
