In this particular situation all the links referred to the same tree source, which had only the information of name, birth death dates and places. It's not a valid source; documents are the valid source. I have all the document sources to add to this profile. Links to the Ancestry tree are just redundant and waste time.
Public libraries usually have access to Ancestry.com. Ours does, but it is required to at the library to access it, not available through the libraries web site.
Right now, I have my Ancestry subscription, so I am able to check.
I wouldn't recommend a complete deletion of any biography, either.
