My latest suggestion report has a 572 error for an early relative. Upon research, it appears to be a discrepancy with date of death, but looking at the image (large copy uploaded to profile with photographers permission), it seems to be the Find-a-Grave transcriber that is in error, not my unsourced family tree. The headstone, to my eyes, definitely says '1876', not '1871' so Find a grave has the error.
However, before I go and send an email to them suggesting a fix, can someone just check that my process and conclusion is correct. It is made a little complicated, in that there are two transcribers for this headstone, one of which is claiming it is a different person, part of their tree, not mine, and we just have an unfortunate coincidence of two John and Hannah Earls, in the same little village within 10 years of each other. I'm not arguing with this Ancestry user, but just going off best evidence.
