Never cite a source unless it was actually in your sight.

It’s simple:

• If you saw a tombstone’s picture on FindAGrave, cite that website–do not indicate you were in the cemetery yourself or took the picture yourself.
• If you saw a transcription of a will in a published book, cite the book and that book’s transcription–do not cite the will itself.
• If your Mother told you something about her mother, cite your mother as the source-do not cite Grandma as you didn’t hear Grandma actually say that something.

Whether the source is accurate is another story. We just want our citations to accurately reflect what used.
