How does a person get started in genealogy?
Start with what you know by writing down parents names and grandparents and then start to gather records or resources to validate your information. One may use a free site such as Family Search or Ancestry, a paid site, but you still have to make sure that all records are accurate.
Using a software such as Family Tree Maker can be helpful to help you keep track of your pedigree charts and records. The library at a local genealogical society, public library or Family History Center can be quite helpful.
Interview your older relatives who are still alive using an audio or video recorder to document their past. Anecdotes such as family histories can be quite helpful to substantiate historical resources.
