In reviewing and merging duplicates, I see that at times, the duplicate person was likely created due to the fact that variants do not show up when I click 'add person' (I test it by adding the info in 'add person' without completing the action, and the variant of the spelling does not show up). Here are some examples of name variants that would ideally show up upon adding any variant of the name:
IE:
-Eliphalet & Eliphelet
-Eben, Eber, Ebenezer
-Ashbel, Ashabel
-Emaline, Emmaline, Emeline, Emmeline
-Benajah, Benjamin, Benji
-Elzear / Eleazar
French canadian:
-Thalie for Nathalie, Natalie
Last names:
Eaton / Eaten
Chamberlin/Chamberlain/Chamberland
These are just a few examples - perhaps this is the best way for feedback?
