Brontë 

surname of the famous family of English authors; the current version is a scholarly convention and until after the deaths of the sisters it was variously spelled and accented. Juliet Barker ("The Brontës," 1994), writes that their father was registered at Cambridge in 1802 as "Patrick Branty," which he soon corrected to Bronte. The family was Irish Protestant. "At a time when literacy was extremely rare, especially in rural districts of Ireland, the usual Brontë name was spelt in a variety of ways, ranging from Prunty to Brunty and Bruntee, with no consistent version until Patrick himself decided on 'Bronte'." [Barker]

praseodymium (n.)

rare metallic element, 1885, coined in Modern Latin by discoverer Carl Auer von Welsbach (1858-1929) from Greek prasios "leek-green" (from prason "leek;" traditionally identified with Latin porrum "leek," which suggests a PIE *prso-) + didymos "double" (from PIE root *dwo- "two").

The name didymia was given to an earth in 1840, so called because it was a "twin" to lanthana. When didymia was further analyzed in the 1880s, it was found to have several components, one of which was characterized by green salts and named accordingly, with the elemental suffix -ium.
