I have a fairly strict policy for how I use information on FindAGrave:
I use the picture of the stone. I cite the source. If it appears that there is a transcription of the stone on the “memorial” page and I have difficulty transcribing the stone from the picture, then I may use the transcription as published on the “memorial” page.
Additional information on the “Memorial” page, including links to parents, siblings, children, etc. is not copied into my genealogical database. I have no way of knowing how the information was obtained, analyzed, etc. If there is a date and place of obituary included, I may use that information to locate the actual obituary. I do not rely on the transcribed copy of the obituary.
I realize that one does not often know where a submitter obtains information. I don’t use database information from WorldConnect, Ancestry.com trees, or other online “trees” in my personal database either.
I use FindAGrave to locate photographs of tombstones in cemeteries that I am unable to personally visit. I find it a wonderful genealogical resource and have located burials that I would have had difficulty locating otherwise. I am grateful for those who take the time to photograph tombstones and place the images on FindAGrave.
I simply choose to only use it for the tombstone information.
Readers, of course, are welcome to use information on FindAGrave as they see fit. Our goal here is to get readers thinking about information, sources, and how they analyze information. Readers are free to disagree–I just want people to think.
Never take anything at face value.
It’s always possible the stone really isn’t in the cemetery that the submitter claims.
