I understand that the Parma royals are mainly of the house of Bourbon. A brother and sister married into 2 reigning families in the early 1900s. Felix married and became consort to Grand Duchess Charlotte of Luxembourg. His sister Zita married Carl Hapsburg who became Emperor-King of Austria Hungary unexpectedly. . Were there others from that country to become consorts or just spouses of other royals and bringing with them the Bourbon influence?
