Kids often create family trees diagrams with the names of their immediate ancestors such as their parents, grandparents and great grandparents.
Many genealogists have posted their family trees on their personal websites.
The family trees in the database have been posted by volunteer genealogists wanting to publish their research.
According to genealogy best practices, names of living people should not be included in online family trees.
However, remember that many family histories or family trees are constructed by well-meaning amateurs; so, you will still have to verify and prove the information is accurate.
