"Ginned up"

[Paul McFedries]

I was asked recently about the first use of "ginned up" or "gin up", meaning
"to engineer" or "to excite." The (RH)HDAS has the original "to liquor up"
sense from the late 19th century, but the more modern senses only from 1973.
That's a big gap. Has it been closed or at least narrowed in the last six
years? None of my other sources even mentions it, and I tried searching the
ADS archives but received a "Method Not Allowed" error.
