Edit: Unsure about the name... Hieronimus connotates too much artist or cronicle writer to me. Hector has a harder pronounciation and a sharper edge to it. Had to do a list of names to work out what to use instead of Hieronimus. Hector, Franz, Hannibal, Hugo, Ignatus, Matthias. Speaking of names - both Gregor Eisenhorn and Titus Endor are such cool names.
Anthor editing of the name. From Hector to Thaddeus. More subtle and mysterious.
