What is the Church's teaching as to what happens to an adult who has attended church - a couple of different churches - and so knows about Jesus but never consented to be baptized?
I don't think my grandmother was baptized. She attended two different churches when family or friends took her (not Catholic) but she would never talk about what she believed and to my knowledge was never baptized.
The Church teaches that Baptism is necessary and that it also brings about the effects of what it says that it does, which is to mark us with an indelible mark of belonging to Him, Christ Jesus.
Since we are all born without God's supernatural life in us, due to origianal sin, Baptism is necessary to open our souls to receive His love into our souls, to wash away original sin so that we can receive this grace.
Obviously, your mother knew Jesus although she didn't talk about her beliefs, she obviously from what you said, she desired to know and love Him and therefore that desire I believe is a form of baptism what the Church calls "Baptism of Desire" and because she was never taught the importance of the Sacraments, she would be protected by what the Church calls, Invincible Ignorance.
