Hello, everybody. My name is Julia, and I am becoming an Internet genealogy addict. I don’t believe in higher powers, except, like, the NSA and the IRS. So I must rely on my failing willpower. Unless you find a rich uncle, Internet genealogy is hard to justify as useful. Why should I care that four hundred years ago, some remote ancestor was a rabbi in Moravia? Geni.com, where I listed my family tree, says it has 74,346,170 people on its site. I’m already up to 1,820 blood relatives.
