Ian: I just now checked the 1841 Ramsey census for John & Ellen Garret, and found them residing at "STRAND Street". There are also others listed on this census that were also on the 1851, living as neighbours of the Garretts, so I'm going to assume that an error was made in the street name and it should in fact be STRAND for both censuses, as all the other information given to me by Sue, Frances and yourself would indicate this as the most probable.
Thanks again for your help - without your suggestion I might not have bothered to check. Lesson learned!
