Welcome to Genealogy Wiki
You can use this site to share your genealogy research with others and work toward building a truly shared family tree. This site is based on the concept of a Wiki which allows all users to contribute and update the shared content.
We are excited to announce that we have released the historical boundary data for counties in 49 US States. That includes over 3,100 counties and nearly 15,000 current and historical boundaries for those counties. This new data builds on the earlier launch of our Interactive Historical map, which allows users to explore places as they were throughout history.
Today we are excited to announce the launch of our new Interactive Historical Map. With this tool, you can view the past using Google Maps-like technology, but with a calendar option that lets you see places as they were throughout history. We believe this will be an invaluable resource for genealogy researchers, students, and history buffs of all ages. We welcome your feedback and look forward to hearing what you think!
