Caslas and Tallulah - Many thanks for your help. Tallulah I do thin tho' that your reference relates to the fact that Barkis is a 'carrier' by profession and not that it is his first name, but many thanks, anyway
He didn't have a first name! I just copied out the entry in Who's Who in Dickens? Thick Book. Yes he was a Carrier. It must be a trick question. All it said was Barkis, Mr. Carrier. It also gives the quotation about "willin'" Everyone else has their first name given if Dickens gave it in the relevant novel.
