I think the amount of sources you had are incredibly reliable and credible. For the one that you had an issue on, I believe you should still use it, and if you still have doubts then look up some of the sources they included at the bottom of the page and use some of them.

The sources that you have are very credible and should all be used to support your topic. They are all related and can make the article much stronger in the end.
