But birth, death, marriage certificates are also not without error - - two examples:
The doctor who delivered my uncle (at home as it was done in 1910) didn't like the name he was given by Granny Nannie for her new son and so, when he did his part for the birth certificate, he put the name he wanted! Uncle Tom and his family didn't find this out for several years and, even then, it was hard to get corrected. The second example is from my husband's grandparents marriage records. When they married his grandfather was 21 and his grandmother was 13 (yes, my eyebrows are sky-high, too) but the Court Clerk signed the paperwork that he personally knew both and that they were over eighteen!
Point being - - it should be left up to the person working the profile to determine what is the best set of sources for their work on each specific profile. We can't sit at the end of some internet connection and say which source is the best or that some sources are never good. There are NO perfect varieties of sources but part of doing our due deligence is determining what we believe to be the best in each instance. And, in some of those instances, a Find A Grave can be better than a birth or marriage certificate. No-one (and I mean no-one) should sit back and automatically say a source is unworthy unless they do the same work the original profiler did. It's too easy to sit in judgement that some sources are not "good enough".
I cannot imagine how it would feel if I was one of the DELIGENT people who spend hours traipsing over cemeteries getting data and taking photos and how they would feel after seeing how ALL work by Find A Tree volunteers is denegratedd over and over and over on this site.
Come one guys, we are better than this continual automatic disparagement of some sites and the work there.
