Fidela Oller Angelats (17 September 1869 - 30 August 1936) - born Maria Dolors Oller Angelats - was a Spanish Roman Catholic professed religious and professed member from the Religious Sisters of Saint Joseph of Girona.Oller was born to potters and lived her life in her town until she set herself on entering a religious order. But the premature death of her father forced her to return home to tend to her mother and brothers though she later returned to the order for her profession and religious life. Oller moved from place to place in service to her order and rendered her assistance to the ill in hospitals where she was known for her attentiveness and comfort.
