It's a long time since you posted your message, so I hope you get this reply. My maiden name was Chaloner. My grandfather told me the Chaloners were originally Huguenot blanket weavers from Chalon-sur-Marne (now Chalons en Champagne), who fled persecution. This is plausible, as Chalons was a centre of such persecution in the 16 and 17 centuries.
The name may be occupational, but neither my grandfather nor I could find a French word 'chalon', meaning blanket. Another possible explanation is that these refugees were simply assigned the name of the place they came from on arrival in England (like Vito Corleone in The Godfather), so that Chaloner simply means 'one from Chalons'. Best wishes, Linda Roberts
