There is a "Saint Celestine" but he was a man. Pope Saint Celestine V was canonized May 5, 1313.
There is also Pope Saint Celestine I (also a man we would hope). He lived in the 5th century A.D.
Pope Saint Celestine I was buried in the cemetery of St. Priscilla in Rome. Later, his remains were moved to the Basilica di Santa Prassede in Rome.
I can find several male saints named Celestine but no saint named Celeste.

His original name as Maewyn Succat but Pope Celestine changed it to Patritius or Patricius before he sent him as a bishop back to Ireland.
Patrick was sent by Pope Celestine I to Britain and Ireland as a missionary but spent most of his life in Ireland.
