Very often I get sent family tree drawings that people have created over the years and passed onto me. These trees provide vital assistance when trying to make links from one family tree to another. Most of these documents do not come with supporting documents and through experience, it can be often more prudent to think that information may not be 100% on them until you can verify the information.
(Please note: These trees are certainly never complete but can be used as a guide when trying to research your own family tree.)
This trees above are Irish based trees, I also have some from Australia, UK and USA which I will post in due course.
