The only thing I can say, is beware of "amazing" trees with info going back that far - it is really quite difficult for most people to track that far back.
AND make sure that any info you see posted or in trees has the source information - without that it is really just heresay.
I hate to say it but the info you find in trees on ancestry or elsewhere is not always correct.
Again - look for their sources. I have seen many trees where someone has just copied from another tree and taken it as truth without checking anything. I have seen that with my own family - amazing really - some of the things I have seen posted for my ancestors which I know is absolutely wrong.
I have found trees - ancestry and elsewhere showing incorrect birth, marriage and death info on various family members of mine - including my Dad and his siblings - showing them born in Minnesota when they were actually born in Manitoba - and death (including year and place) of a cousin who is still very much alive!! -just two examples.
Sometimes I contact the person with the tree and generally it turns out they just copied the info from someone else, assuming it to be correct.
I always find it better to do my own searching OR at the very least search for the information to confirm or dispute the info.
Having said all this, let me know if there is someone I can look up for you - I promise that if I find anything I will show you the source for the info.
