Crown Prince Carol with his first wife, Joanna "Zizi" Lambrino, a daughter of a Romanian general whom he wed on 31 August 1918 in Russia. Since she was a commoner and a Romanian the marriage violated Romania's constitution and Carol's father, King Ferdinand, forced an annulment 7 months later. The couple continued living together, however, and they had a son, Mircea Gregor Carol Lambrino, on 8 Jan. 1920.
