Stump the German

[Eva Elisabeth]

(Thanks!) Incredible, I was sure this would need more hints! You absolutely stumped me, Roger!

Allegedly Lincoln green was a popular color during the Victorian period, and Mary mentions the color as follows in a letter to Mercy Ann Levering, written in Springfield, Dec. [15?] 1840:
"Speed's 'gray suit' has gone the way of all flesh,..., Lincoln's Lincoln green have gone to dust..." (J.+L. L.Turner: "MTL-Her Life & Letters".)

Here's the background info on the color's name:
