coon (n.)youdaoicibaDictYouDict[coon 词源字典]
short for raccoon, 1742, American English. It was the nickname of Whig Party members in U.S. c. 1848-60, as the raccoon was the party's symbol, and it also had associations with frontiersmen (who stereotypically wore raccoon-skin caps), which probably ultimately was the source of the Whig Party sense (the party's 1840 campaign was built on a false image of wealthy William Henry Harrison as a rustic frontiersman).

The insulting U.S. meaning "black person" was in use by 1837, said to be ultimately from Portuguese barracoos "building constructed to hold slaves for sale." No doubt boosted by the enormously popular blackface minstrel act "Zip Coon" (George Washington Dixon) which debuted in New York City in 1834. But it is perhaps older (one of the lead characters in the 1767 colonial comic opera "The Disappointment" is a black man named Raccoon). Coon's age is 1843, American English, probably an alteration of British a crow's age.[coon etymology, coon origin, 英语词源]
HarryyoudaoicibaDictYouDict
masc. proper name, a familiar form of Henry. Weekley takes the overwhelming number of Harris and Harrison surnames as evidence that "Harry," not "Henry," was the Middle English pronunciation of Henry. Compare Harriet, English equivalent of French Henriette, fem. diminutive of Henri.
log (n.1)youdaoicibaDictYouDict
unshaped large piece of tree, early 14c., of unknown origin. Old Norse had lag "felled tree" (from stem of liggja "to lie"), but on phonological grounds many etymologists deny that this is the root of English log. Instead, they suggest an independent formation meant to "express the notion of something massive by a word of appropriate sound." OED compares clog (n.) in its original Middle English sense "lump of wood." Log cabin (1770) in American English has been a figure of the honest pioneer since the 1840 presidential campaign of William Henry Harrison. Falling off a log as a type of something easy to do is from 1839.
