'And' Saint Barbara is 'shared' by Military Engineers and a whole host of others...
Her imprisonment led to her association with towers, then the construction and maintenance of them, then to their military uses - hence, Engineers.
The lightning that avenged her murder led to asking her protection against fire and lightning, and her patronage of firefighters, etc.
Her association with things military and with death that falls from the sky led to her patronage of all things related to Artillery, and her image graced powder magazines and arsenals for years.

St. Patrick - as the patron saint of engineers, is credited with fostering the development of arts and crafts and introducing the knowledge of the use of lime as mortar in Ireland.
He is also responsible for the initial construction of clay churches in Ireland in the 5th century A.D. Another of St. Patrick's achievements was teaching the Irish to build arches of lime mortar instead of dry masonry.
These beginnings of ceramic work developed into organized crafts, and that's how St. Patrick became the patron saint of ceramic engineers, as well.
King Saint Ferdinand III of Castile - is the patron saint of persons in authority (rulers, governors, magistrates, etc.)--a result of his wise appointments; the poor and prisoners (over whom such persons rule); engineers (a result of his technical military skills), and the Spanish army.
