I disbelieve in the Hannah Dusenbury theory for the following reasons:
Hannah was born 1759 which would mean she was 6 when Nathaniel was born. She married a William Wright alright, but he was listed as a doctor in the above mentioned source and why when he got to PEI would he be be a shoemaker if he had been a doctor in New York? For the above 2 reasons I can't go along with Hannah Dusenbury although it would be marvelous because the info on her family goes back to the 1200's.
