1) Determine where your ancestral families were on 16 May 1865 - 150 years ago.
2) List your ancestors, their family members, their birth and death years, and their residence location (as close as possible). Do you have a photograph of their residence from about that time, and does the residence still exist?
3) Tell us all about it in your own blog post, in a comment to this post, or in a Facebook Status or Google+ Stream post.
