What do Genealogists do?
they study gene pools and DNA and stuff they study that ya know
There are professional genealogists that will do research in exchange for money. They usually charge a fee by the hour and may want travel costs and materials costs. They should be certified by one of the organizations. Most of us do it for free because we are working on our own families and we like it! It is sort of a detective story!
No religion has records of all people, but the Church of Latter Day Saints, the Mormons, compile genealogical information from records worldwide on any person, not just Mormons. They gather information from gravestones, church records, newspapers, other genealogists and pretty much any source they can find. They make the database available online and it is used extensively by many genealogists.
