Other canon notes and references
Lucas is either a Latin name derived from Lucius (lux "light") or from the Greek Λουκας (Loukas, Loukanos) "man from Lucania (in Southern Italy)" (Behind the Name).
Picquery is of unknown origin, but Lucas shares the surname with Seraphina Picquery, a President of MACUSA in the 1920s.
As he comes from the USA, Piquery may have attended the Ilvermorny School of Witchcraft and Wizardry.
