It could also be pronounced Mag-duh-lee-nah which to me is better than the other pronunciations.

We pronounce this name 'Magdalehna' though some people say Magdaleeena. We named our third daughter Magdalena Maria, in honour of Mary Magdalene... Feastday 22nd of July for Orthodox and Catholics alike.
