It's a good morning to do genealogical research, exploring things on Internet. I have found many wonderful maps that I feel enhance my research. I have been looking for outline maps for a lecture that I'm presenting. The Perry-Castaneda Map Collection has many links to useful map sites, many of which are educational maps for students. I have also found helpful information and maps at 13 Originals Founding the American Colonies. Part of my lecture pertains to the formation of the colony of New Jersey. I needed a map showing West Jersey and East Jersey which I found at Where was the West Jersey/East Jersey line?. Actually there are several maps at that site.
Maps help your research come to life. They help you visualize routes that your ancestors may have taken in their migrations, where their land was located on old maps, plus where it is within today's boundaries. It's a snowy day to find more maps on Internet, so I have several hours of fun ahead!
