May 23, 1999 4:46 p.m. EDT Mormon Church Puts Genealogy Data Online Salt Lake City-AP -- You can get everything else on line, so why not your ancestors? A new Web site put up by the Mormon Church officially kicks off tomorrow. It will contain links to 400 million names of people -- going back to the year 1500. Also, the Church of Jesus Christ of Latter-day Saints' will add millions more names later this year, using its records on two billion dead people. The Web site has been accessible since the church began testing in April. A new and improved version will be unveiled formally tomorrow in Salt Lake City. The creator of a popular index of genealogical Web sites calls this a ``real boon.'' And Cyndi Howell of Washington state adds that the new Web site is like ``bringing Disneyland into your home.''
