Question

How can I find unsourced profiles in a particular place like Maine

Answer 1

You can start here https://www.wikitree.com/wiki/Category:Maine_Unsourced_Profiles

Or here https://www.wikitree.com/wiki/DBE_UnsourcedList_ME

Or here for more places https://www.wikitree.com/wiki/Space:DBE_Unsourced

Lots of the time you can also find profiles that lack sources but don’t have the unsourced tag if you look here https://www.wikitree.com/wiki/Space:DBE_Errors_By

Answer 2

There is a category: Category:Maine_Unsourced_Profiles

I don't know if there is way to search by location.
