There will be an upcoming program on PBS on March 4th at 3 AM called "FACES OF AMERICA, Know Thyself". It has to do with the latest on DNA. There are Hollywood stars that learn about their family histories thru their "spit". It might be worth watching or taping where you can see it later. I did verify this on line with the PBS website. Another program along the same theme is "Who Do You Thing You Are" - It's Friday, March 5th at 8 pm Eastern and 7 pm Central - NBC Jane Foley SC
