The Family of King Constantine I of the Hellenes (Greece) [supersized].
Constantine, called ‘Tino’ in the family, was the eldest child of King George I and Olga Konstantinovna. His name was welcomed by the Greek people as there was a legend that a Greek King Constantine would reconquer Constantinople, but he was most likely named after Olga’s father, Grand Duke Konstantin Nikolaevich. Tino, along with his brothers George and Nicholas, was a first cousin and friend of Nicholas II.
Tino’s wife was Sophie, a sister of Kaiser Wilhelm II, and they had six children: George, Alexander, Helen, Paul, Irene and Katherine (not pictured). Helen married Carol of Romania, who had been suggested as a possible husband for OTMA. All three sons ended up being Kings of the Hellenes with the second son, Alexander, reigning first under unusual circumstances.
