While I've seen some very odd tombstones, I thought this would be an opportune time to remind new genealogists that, although the information on tombstones and death certificates (DCs) is primary source information, it isn't alway correct. Remember, the deceased is not around to supply the information for the carving (unless he had it made before his death) and can't supply information for the DC. I've seen many DC's and tombstones with erroneous information. If the information can be proven wrong, leave a notation of such in your researchers notes in the profile.
Also, for the beginners, a findagrave memorial without a picture of a gravestone, or other data such as an appended obituary or DC, isn't really a valid source of genealogical evidence. Descendants often create such memorials and enter unsupported claims. So, try to find some valid sources before starting a profile based solely on such a memorial.
Happy hunting people. Neat question BTW.
