John67x, that is really neat. Family trees are like birthdays. Everyone has one and they are all different.
I have recently discovered the tv show Who Do You Think You Are on TLC. With the magic of television, Ancestry.com, and producers, they take celebrities and walk the celebrity through the research of their family tree. Of course the producers have done their homework and found an interesting facet of the family tree to focus on. Many of the celebrities get teary eyed when they discover the hard ships and sacrifices someone made to secure their future.
In addition to a history lesson, I think the show informs people of different archives, records and data bases that they can use to trace their trees. Sadly, African Americans have to utilize slightly different research methods, but that's informative too!
In case you can't tell, this is my new favorite show.
