This is a series on our PBS network hosted by Professor Henry Louis Gates. Each show is typically two or three celebrity guests, who each sit across a table from him, one on one, while he presents each of them with a "book of life" that represents the family history research performed by his team. One of the guests this week was comedic actor, Andy Samberg, whose mother was adopted and has spent decades looking for her birth parents. She had a couple of letters from the adoption agency that had very vague descriptions of her birth mother. The only details that looked hopeful was that she was Jewish, and had a sister who was a famous singer in India. With just that and DNA, the team narrowed the list to one family, then just one woman, attaining a photo, that didn't exactly match the vague description, but close enough. Then they went back to the DNA looking for the father. They started with that he would have come from a particular area in Sicily, and found a potential match to a man who served in the U.S. Navy and was located in the same area as the birth mother at the crucial time. When they showed a photo of him in his youth, he looked remarkably like Andy Samberg! So we watched a "reunion" of Mrs. Samberg and her new half-sibs. They showed her photos and told stories. Then they pulled out a photo of their dad with a woman they could never identify. It was the birth mother! Isn't that wonderful? For 70+ years she never knew who her parents were, they never married, and then here was a photo of them together. Very compelling story. They are not all that good, but that one was pretty special.
