Don't know them, I'm a volunteer researcher. Well either there are two Eulons - and you are saying no to that - or one of the two burial places is wrong. I'll leave you to sort that out, okay? Since you are family. You can contact the Find a Grave creator to ask about the memorial or request that he change it.
Sometimes Find a Grave creators are family members but usually they are not. Their information is most often based on local information about burials, such as cemetery records and or notes they've taken while walking a cemetery. Find a Grave is a resource for family historians, as a headstone is considered a very strong piece of evidence in establishing the date of death for an individual. Place - not so much. People are not always buried in the place where they died. Find a grave creators are trying to help individuals locate "lost" grandparents and great-grandparents. Finding a burial place can be very meaningful to a family. Okay, nuff said. Glad you connected with family here.
