As a researcher, you should never believe what you find as secondary sources. In the end you must consult the original documents to check for accuracy.
There is an incredible amount of inaccurate genealogical rubbish on the internet. Look at a lot of Ancestry trees. They assume that someone born at the same date is the same person, even though they were born in different counties. Nor should you believe anything you are told in here (including my suggestions) without checking them out. Otherwise you will end up with a purely fictitious family tree.
