A Derivative Source Provides Secondary Information Used as Direct Evidence

One of the documents used in issue 23 of Casefile Clues is a transcription on FamilySearch from an Iowa death certificate.

It is a derivative source because it is a transcription.
The information we used from it was secondary.
And the evidence was direct.

Those statements are made using definitions as given by Elizabeth Shown Mills in "Evidence Explained." Those definitions serve our purposes well. However, I'm not certain Mills ever really defines "information." Personally I think "fact" or "statement" works a little better.

Making definitions is easy. Creating a road map for how information is analyzed is much more difficult to do. We look at conflicting information in issue 23 and sort out two individuals who aren't as similar as some think they are.

Join the discovery and subscribe to Casefile Clues. Your ancestors are waiting--just make certain you find the right ones.
