WolframAlpha does genealogy

23/06/2010

Getting tangled up in your family tree and confused about how all those people are actually related to you?  The search engine WolframAlpha will calculate family relationships for you.  For example, entering "father's cousin's daughter" gives the result "second cousin", accompanied by a genealogic tree diagram illustrating the relationship.  Read about this feature on the WolframAlpha Blog and try it out on the search page.
