I was raised Catholic in a fairly typical post WWII Catholic family. More than two kids, Catholic schools, Mass on Sunday and Holydays. I don't remember my parents as being especially religious, but the Church was definitely part of our lives. We didn't do any of the social stuff, but we never missed Sunday Mass and the Bible and rosaries were present in the house.
I don't recall an especially close relationship with my maternal grandparents, my grandfather died when I was 6 and shortly after we moved far away from where my grandmother lived, but they must have had an influence. They were Irish, first generation American, and I picked up from them a little Celtic lore, mostly banshees and little people. I took this sort of thing to heart, to the dismay of the nuns during my early days in parochial schools, before I learned to shut up.
