This press release from BYU caught my geeky eye:
The group of computer science students developed a Facebook app called “Relative Finder.”
Most other genealogical Facebook applications are based only on your living family and at best can connect you with third or fourth cousins. The Relative Finder app goes back an average of nine or ten generations because it connects to the genealogical information [in new FamilySearch].
It can even show you your relationship to famous historical figures like the signers of the Declaration of the Independence, apostles and prophets from the early days of the restored church, American presidents and many more.
