There are a lot of county names where the French version seems like an import error occurred, dropping the apostrophe.
For instance: « Comté d'Union » has become « Comté dUnion », or « Comté d'Huntington » has become « Comté dHuntington ». There are 224 such mistakes according to:
Code:
SELECT
id, geoNameId, lang, name
FROM
geo_alternateNames
WHERE
lang = 'fr'
AND name LIKE 'Comté d%'
AND NOT name LIKE 'Comté de %'
AND NOT name LIKE 'Comté du %'
AND NOT name LIKE 'Comté d''%'
I tried deleting a few, but this would be faster to automate.
