No one can be sure without a birth,marriage or deceased record. Maybe you can find some who has access the the CBG but you will need to know where and when she was born plus the name of her parents, maybe where she got married? Since you say she was born in 1924 you probably won't find any public records yet.
CBG has a lot of information but I think you need a special permission card to find the information that is on file and not public. Since you are family maybe someone can help but I can't.https://cbg.nl/
