Thanks Charani & Ron I think I will just use the research notes when I need to clarify proof. Ron, I will adopt your probability approach when I have "negative proofs" as I agree entirely with you on that.
Why I am doing this... I am trying to look at my Family Tree as if a descendant 2+ generations later picked up the tree and wondered why I chosen certain parents when there were other candidates. Also I am aware that variations on some lines in my tree exist on the web that I do not agree with (especially in ancestry). I want to document exactly why I made my choice, which for the most part rely on positive sources (baptismal and marriage records). Where I have the 'Negative proof' what I can do is prove it is Not the choice others have made in their trees. Taking on board Ron's comments this would increase the probability of my choice but not prove it. I gave up long ago in trying to correspond with people who showed these erroneous links, as their response, if any, was to cite the other trees that greed with them.

Alan, I can see where you are coming from, but I have not found the need to do extensive work on this, with respect to pretty well all my family, who are readily identifiable from the sources available. There is one exception (my 5 G G grandfather) where I have been unable to find a source which links him to the person who I feel sure is his father. I have an extensive ToDo on him detailing all the sources I have checked, and when, and I still regularly make checks to see if anything has cropped up. The person I am sure is his father is there because there is nobody else I can see who could be, and other evidence indicates he is the most likely candidate anyhow. However, I do not accept the concept of "negative proof". This is often a concept used in ignorance by the media, often in the concept of a new medical treatment, asking for proof that there are no adverse effects. This can *never* be proven, only the probability range can be stated. Similarly one can never say that negative proof can be used to define a relationship - only the likelihood. In the case of my relative, it is possible, albeit unlikely given other evidence, that his parents were just passing through the town at the time he was born. DNA may resolve the question, but at the moment I have no contact who would serve to confirm the relationship.

Anyhow, I decided to send it as my reply is not quite the same.

My initial throughts were to create a document as a backup source detailing these proofs. Then again, why not just use the research notes. Just wondering what others do...
