Our Timelines is a free website that generates a timeline of historical events that happened during a person's life. For example, I typed in a few of my great-great grandfathers, Francis Edward Abbott and George W. Sherlock, with their birth years and death years and this is what appeared for their timelines.
Francis Edward Abbott (black & white timeline - printable)
George W. Sherlock (color timeline)
Our Timelines is a great resource for genealogists..."For Genealogists, these capabilities are a veritable gold mine - you can actually see how a family member fits into history, and that not only helps users of your genealogical efforts to know these people a lot better, it helps you to better direct your research."
You can also add 10 personal events into your timeline as well: marriage, graduation, children, etc. Plus, any event that is underlined links to more information on that event. I think this a great learning tool, as well as a great genealogical tool.
