De la Finada

I've found the phrase, "de la finada" recently in some marriage records and I'm not familiar with the phrase. It typically appears in front of a mother's name when naming parents in a marriage record. Like, "Jose Mendes y la finada Dolores Zamora..." It sounds like a reference to someone being deceased, but I've not previously seen or heard that term so applied and could not get any of the online translators to confirm.

Can anyone tell me if I'm on the right track?

Thanks so much!
