There is alot of assumtions out there. Granted, primary documentation cannot always be found when you get that far back, due to fires, wars, natural disasters, ect, but if something is assumed through a preponderance of evidence and studied research, but not positively proven, it should be stated as such, and given the reasons why this conclusion was reached. I have been trying to do that myself as of lately. Genealogy should be treated more as a science, and less as a game. What is the purpose of it, if not to prove our true family linage, otherwise, it is meaningless. I do not trust anything, just because it is in someones tree, unless they can give me the reason for it. Way to many times I have contacted tree administors inquiring as to where this data came from, just to be told that they got it off someone elses tree without any proof. So many people grab onto whatever they find, without proof, and put it into there trees, and spread it to others as fact. This is especially true when it comes to nobility, because they are notable people, and there is much written about them. Everyone, wether they admit it or not, wants to be connected to famous people, such as Earl Spencer Compton. Even though it has been proven beyond a shadow of a doubt that something is not true, they refuse to let go of it, and so the falsehood perpetuates. Think about it, not everyone that lived in the past was a king. There were thousands more commoners than there were nobles. Just because they had a surname in common, doesn't mean that they were at all related. DNA is the best way to positively prove a relationship. I hope that more dedicated scientific family finders start using it.
