In July of 1965, a daughter was born to the last Greek king, Constantine II, and his wife, Anne-Marie of Denmark.
The new Greek princess was named Alexia “after the Byzantine Emperor Alexius, who ruled from 1061 to 1118.”
Alexia was a favorite name of King Constantine’s father, Paul, who died in March 1964, the officials added. King Paul had intended naming Constantine’s younger sister Alexia, but she was born during the war and was christened Irene — Greek for peace — instead.
Unlike most other royal babies in Europe, Greek royal babies traditionally received just one name.
