Welcome Gorgia!
To answer your question, yes. Former born-in myself, my grandmother heard that knock at the door under very similar circumstances. She bought the family into the cult, I was the last surviving member when I decided to exit back in the late 90's.
I've often wondered what would have happened had she not converted to the JW's. I used to fanticise during the meetings that my family had never known the "truth". It got me through some pretty mind numbing times.
