"coffee," by 1932, likely derived from Java, a noted source of fine coffee, as explained in the glossary of naval terms in Robert P. Erdman, "Reserve Officer's Manual, United States Navy" (Washington, 1932). The guess that it is from the name of U.S. coffee merchant Joseph Martinson (c. 1880-1949) is not chronologically impossible, but it wants evidence and seems to have originated in the company's advertisements (1972).
Earlier in American English (1772) it was the colloquial name of a Portuguese or Brazilian coin worth about $8, shortened from Johannes in this sense (1758), the Modern Latin form of Portuguese João (see John), name of a king of Portugal whose head and Latin inscription appeared on the coin.
"stale joke," 1816, from Joseph Miller (1684-1738), a comedian, whose name was affixed after his death to a popular jest-book, "Joe Miller's Jests, or the Wit's Vade-mecum" (1739) compiled by John Mottley, which gave Miller after his death more fame than he enjoyed while alive.
A certain Lady finding her Husband somewhat too familiar with her Chamber-maid, turned her away immediately; Hussy, said she, I have no Occasion for such Sluts as you, only to do that Work which I choose to do myself. [from "Joe Miller's Jests"].
"online journal," 1998, short for weblog (which is attested from 1993 but in the sense "file containing a detailed record of each request received by a web server"), from (World Wide) Web (n.) + log (n.2). Joe Bloggs (c. 1969) was British slang for "any hypothetical person" (compare U.S. equivalent Joe Blow); earlier blog meant "a servant boy" in one of the college houses (c. 1860, see Partridge, who describes this use as a "perversion of bloke"), and, as a verb, "to defeat" in schoolboy slang. The Blogger online publishing service was launched in 1999.
alcoholic drink made with carbonated water and lime juice, 1895, American English; in contemporary sources reputedly from the name of "Colonel" Joseph K. Rickey (1842-1903) of Callaway County, Missouri, Democratic lobbyist and wire-puller, who is said to have concocted it to entertain political friends.
And as long as there is thirst and limes, or lemons and gin, so long will the Honorable Joe Rickey be remembered in Missouri and his famous beverage tickle the palates of discriminating citizens. A hundred summers hence Joe Rickey will be called and Champ Clark and DeArmond forgotten. [The Conservative, Nebraska City, Neb., July 6, 1899.]
by 1926, "mediocre prizefighter," of unknown origin, credited to U.S. sportswriter and Variety magazine staffer Jack "Con" Conway (1898-1928), who might at least have popularized it. Non-boxing sense of "average person" is from Joe Palooka, hero of Ham Fisher's boxing-themed comic strip, which debuted in 1930.
trivial term of endearment, by 1910, from the name of the baby added in 1907 to the popular "New York World" comic strip "The Newlyweds" by U.S. cartoonist George McManus. The name is perhaps from Snooks, proper name used in Britain for "a hypothetical person" (1860; compare Joe Blow in U.S.). As an actual proper name, Snooks dates back to the Domesday Book and may be from Old English *snoc "a projecting point of land" (perhaps here with sense of "a big nose").
