While we once had an article on the OHiggins clan it didnt cite reliable sources backing up the information such as textbooks on Irish history or articles in reputable magazines In fact it gave no indication that the various OHigginses actually all belonged to the same clan Thus what could be used of it was merged into the article on the family  You can use the Article Wizard to write a new draft that summarizes what such sources report about the clan Please note that we also have an article entitled  hUiginn though that too is in dire need of work  right now it basically duplicates OHiggins surname
