Why do they do this? I know that it is open to debate sometimes what is correct, but...
Copy and pasting random stuff, most of which is obviously not correct. ie. 3 baptisms before birth different areas of the country. mixed up life events and living to 140 are some recents I've found from Ancestry family trees.
Why do genealogy then not research or at least read what your tree pages? A lot of them don't make sense.
