I already knew about the Disproven Existence Project but put that aside because it is for individuals, not for places. I would like to see a Disproven Place sticker which would be referenced to a detailed explanation, properly sourced.
Would you mind having a look at https://www.wikitree.com/index.php?title=Space:Richley%2C_Anglesey&public=1 for me and give your comments/views. I have tried to reduce my research to a dull roar!!
Cheers and take care
I have asked Ros to comment, I would also appreciate your views.
Nice piece of research.
I would suggest that the category be named for the correct location name, with variants noted, and your page be linked to it. And take a look in FamilySearch to see if they have any actual records for such a location.
