The problem is in this part of the world, there are so few local mappers to update the map that apart from a few hotspots, actual mapping errors remain for years unchanged, and great empty spaces remain.
Add to that the fact that of regular real mappers, the data from neis-one I have seen imply that for every ten-or-so mappers in the world, perhaps one single mapper actually looks at and resolves notes/bugs.
So it's extremely unlikely that any local user will ever see these questions.
More than likely, a remote armchair mapper halfway around the world will respond, as I have done, using text searches via g00gle to attempt to point to a resolution.
It would have helped here to point out the two differing names, which sometimes is not obvious -- particularly for someone who does not know what  to look for.
And perhaps mention, inconsistent TIGER data, so it is clear why you ask.
By the way, going by popularity, I get under a hundred search results for Chalfant, with several hundred for Chalfont, the former largely realtor listings, the latter with far more variety.
However I would not feel confident from just these search results to claim the last segment in TIGER is incorrect.
Of course, if using search results to disprove one of them based on non-OSM sources is not allowed, then you cannot do it, and as a distributed-DOS version of your prohibition, I should not either.
