I'm working through the Pope's Project and have come across a profile that already existed for Pope Honorius IV (Giacomo Savelli). Currently I am just creating profiles for each pope, adding the succession box and categories. It is my intention to come back and complete the biographies once I've completed this initial task.
When I arrived at Pope Honorius IV the profile was already created (as are occasional ones in the pre1500s category. However, it has him linked as a brother to Maria Savelli. She was born over 60 years after him so brings up an error when saving. I've added a Research Note to this effect as I don't have time right now to follow up on the validity of this information.
If there is a pre 1500s certified WikiTreer out there who would like to take a look at this one I would appreciate it. If not I've noted it on the Pope's Project page as an error that needs to be validated and corrected and I will get back to it eventually. There is a lot of biography building to do on the Popes and it is going to be time consuming. Any help would be appreciated.
