US census records boost geneological database

An Internet company is adding US Census records to boost its archive of searchable names to 5 billion, which it says is the most comprehensive genealogical database ever compiled. Ancestry.com planned to announce Thursday that it has copied complete census records from 1790 to 1930, making it the only searchable, online repository of the documents. The US government waits 72 years before releasing original census documents. Copying the material took a team of experts and workers a combined 6.6 million hours of labor, Ancenstry.com said.
