The Ancestry website is not as credible. Generally. they do not fix problems. There are some duplicates of names. I've used that website. My family have too. I've seen inaccurate information with names, dates, locations, and other information.
.
Wiki Tree is more about working together as a community to build family trees and to build archives of informations and things that can be shared and edited and worked on.
.
But Ancestry is more focused on making money more than they are with building archives that can be accessed freely, publicly, globally.
.
Some of Ancestry may be true or partly accurate. Some of it is true. You have to be careful.
.
But Ancestry is not like a Wiki Pedia or a Wiki Tree kind of website where people edit the mistakes that others made.
.
Wiki Tree has a better system for building genealogies, as in family trees, for collecting the information, for organizing it, for adding sources to help authenticate it.
.
Some websites like Ancestry require money or maybe too much money after you're free trials end and the work you do or find on those websites are sometimes not accessible when you're not giving them money.

Some websites like Wiki Tree are more credible when they allow for the ability to edit mistakes.
