Did you know...
Many states provide you with death records for FREE online via indexes and archives? For example, Vermont indexes all their death records that are more than 5 years old - entirely online!
I didn't know any of this stuff, and when I was doing my own genealogy and ancestry research I paid a pretty penny to learn about my heritage. Check out www.findfreedeathrecords.com to learn about the nuances before you decide to pay for any death certificates. Even if your state isn't one of those with a free archive, chances are you can get certificates from the state for much less than what the online sites are offering.
