Does anyone know of a source, preferably online, that summarizes the history of the Habsburg coat of arms? I seem to recall that the original Habsburg shield was a red lion rampant on a gold or yellow shield. This was combined later with the shield of Austria, red-white-red stripes. Lastly these were combined with the shield of Lorraine, a red diagonal stripe on a gold shield, with three white birds some sort on the stripe. Does any of this sound correct? Thanks.
