CBS News has a story about a new kind of genealogy: finding extended biological families in a manner that no one ever anticipated or dreamed possible until recently. Correspondent Steve Kroft reports that these families are made up of something called "donor siblings," apparently a new term to genealogical dictionaries.
Every year an estimated 30,000 children are born in this country to mothers who have been artificially inseminated with sperm from an anonymous donor. Most of these children grow up never knowing their biological father - but now, with the help of sperm bank records and the Internet, some of them are finding half-brothers and half-sisters they never knew they had, who were sired by the same anonymous donor. These children are forging family ties they never knew existed. In other words, they are acting like traditional genealogists.
