When I was in the Dutch Royal Horse Artillery, all their guns were named after places where they did battle ( most from the Napoleontic wars ), so we had names like: Stralsund, Friedland and Bergen.
Still, there was one oddity in this system: Number 225, from the 1st battery, bravo platoon is called Barbara, after the patron saint of the gunners.
I am pretty sure there are some tanks around somewhere that are called 'George' after the cavalry patron saint.
hth,
