In THE PRIVATE JOURNAL OF WILLIAM REYNOLDS: UNITED STATES EXPLORING EXPEDITION, 1838-1842, by William Reynolds, Nathaniel Philbrick, and Thomas Philbrick, there is mentioned, on page 97 (Penguin Edition), that

        "Many of the girls at Point Venus [Tahiti] have learned the chorus songs common with sailors in heaving up the Anchor & other work...Their voices were good, and the ditties of "So early in the morning the Sailor loves his bottle oh," "Round the corner, Sally," "Tally Ho, you know" & a dozen others were often heard along the beach for half the night." (sometime between September 18th & 24th, 1839)

Two of these songs are also mentioned by Dana: "Round the corner, Sally," and "Tally Ho, you know".

And here is a somewhat similar account from 1844, from Edward Lucett's book ROVINGS IN THE PACIFIC, FROM 1837 TO 1849. The event is recorded for August 19, 1844 at Huaheine, in the South Pacific. Lucett says,

        "I was desirous of procuring the original [words], and took a person well skilled in the language to write them down for me; when, to my great surprise, I discovered that both the words and the air were a beautiful modulation of our sailors' song of "Round the corner, Sally!" (p. 82)

In 1843, Dan Emmitt wrote and published a blackface minstrel song called "My Ole Aunt Sally". It has a concluding phrase in the chorus that goes "Ra, ree, ri, ro, round the corner, Sally." Here is the publication information:

And here is "My Old Aunt Sally":

Once again, it is hard to know whether the chanty borrowed from the minstrel song or vice-versa. But since we have documentation that notes the existence of "Round the corner, Sally" as a chanty that predates Emmett's song, it may well be that he borrowed the phrase from the chanty. Or it may be that both the chanty and Dan Emmett borrowed the phrase from an earlier Black corn-shucking song, here:

I'm not sure of the dating on this, but it is another account of "Round the corn, Sally" as a corn-shucking song:
