In reference to U.S. president Abraham Lincoln (1809-1865), Lincolnesque is from 1894 (earliest reference is to the beard); Lincolniana is from 1862.
a name originally applied to the lake, perhaps from Old Ojibwa (Algonquian) *meshi-gami "big lake." The spelling is French. Organized as a U.S. territory 1805, admitted as a state 1837. A resident is a Michiganian (1813); Michigander (1848) seems to have been a humorous coinage of Abraham Lincoln in reference to Lewis Cass.
Think on these things, and let S______ go to Lincoln sessions by himself, and talk classically with country justices. In the meantime we will philosophize and sentimentalize;—the last word is a bright invention of the moment in which it was written, for yours or Dr. Johnson's service .... [Laurence Sterne, letter to William Combe, Esq., dated Aug. 5, 1764, published 1787]
c. 1600, "flaps formed by the lower back of a coat," from coat (n.) + tail (n.). In 17c., to do something on one's own coattail meant "at one's own expense." Meaning "power of one person," especially in politics, is at least from 1848 (in a Congressional speech by Abraham Lincoln); expression riding (someone's) coattails into political office is from 1949.
But the gentleman from Georgia further says we [Whigs] have deserted all our principles, and taken shelter under General Taylor's military coat-tail, and he seems to think this is exceedingly degrading. Well, as his faith is, so be it unto him. But can he remember no other military coat-tail under which a certain other party have been sheltering for near a quarter of a century? Has he no acquaintance with the ample military coat-tail of General Jackson? Does he not know that his own party have run the five last presidential races under that coat-tail? And that they are now running the sixth under the same cover? Yes, sir, that coat-tail was used not only for General Jackson himself, but has been clung to, with the grip of death, by every Democratic candidate since. [Lincoln, speech in Congress, July 27, 1848]
Sockdologising likely was nearly the last word President Abraham Lincoln heard. During the performance of Tom Taylor's "Our American Cousin," assassin John Wilkes Booth (who knew the play well) waited for the laugh-line "Well, I guess I know enough to turn you inside out, you sockdologising old man-trap." Amid the noise as the audience responded, Booth fired the fatal shot.
