Yes, I've always wondered about Barnabas's lack of an English accent. Do you s'pose the cultured, well-bred tones of his voice simply fooled the Collins family into believing his story?
Any generation of Louis Edmonds characters had a stronger British inflection(transmuted from Southern) than Jonathan Frid's (Canadian-to-England-to USA), and THEY were SUPPOSED to be All-American. 1795's practically accentless Daniel grows up to be afflicted and inflected 1840 Daniel, with no backstory to explain that, perhaps, he has spent quality time in England himself, while growing up.
Also then too - in this storyline Julia's posing as his sister. Where's HER English accent? I guess she lost it during her time in Pennsylvania?
Jah, she should have arrived sounding like Pennsylvania Dutch. ("We Collinses catch different accents with the ease that some people catch a cold.")
But again, referring to Brothers with accents and Sisters without, there was precedent,
in the Roger-- Elizabeth relationship (and any permutation of Edmonds and Joan Bennett characterizations.) Elizabeth DOES sound highly refined and cultured and a bit stilted, but still, it's American upper-crust. J. Bennett's 1795 Naomi sounds less British than her husband Joshua, though in THAT period, it might be assumed that both had more contact with actual English, and might even have spent time there (at least prior to the Revolution.)
To make matters even MORE confusing, Joshua's sister (never made clear if she was younger or older) Abigail sounds more New England than anyone, and much younger brother Jeremiah has NO accent whatsoever. Neither does his daughter Sarah, but his SON does (even though it seems BARNABAS had been spending a lot of time "brushing up on his FRENCH"!)
