Thanks so much for the response. You said exactly what I was suspecting and I have already found proof of thats the case. Fortunately I know my family line well enough now that I can see misinformation Most of the time; but not all. Doing the math and seeing places, states and so forth also give me the clue that this 'john' was a son of an uncle but not my relative that was married to this particular woman. Ya know. So yes, I was seeing that but was hoping there was ALSO a way via Ancestry or Family Tree Maker where a person, if so inclined, could also purchase the proving documentation for our personal files. But looks like - not.
Thanks again for your supporting answer though.
