Bosco Family History

Italian: topographic name for someone living or working in a wood, from Late Latin boscus ‘shrub’, ‘undergrowth’ (of Gallic or Germanic origin), or a habitational name from a place named with this word. De Felice suggests that in some cases it may have been an occupational name for a woodsman or forester and, by extension, a nickname for a surly or rough person.
