Could the name you remember possibly have been spelled "D'Andraka" or "D'Andraca"?
You mentioned that this was the name of a Spanish woman, and D'Andraka (or D'Andraca) in the Basque language means: "from the hill of the lady".
Both Andraka and Andraca are Basque surnames, but they can be used as first names, too. Here is an online reference I managed to find for you:
