Same thing about my dad's family...very old school, very hard nosed. They lived in a house during WWII that was a two-family house. The owners were Italian and they got along very well with eachother. Anyway, the house was haunted. I heard my grandmother and dad tell on multiple occasions that there was something "wrong" there. For example, my grandmother put a statue of Mary in their bedroom, and one night my grandfather woke up and saw a dark figure wearing a shroud praying to the statue, at which point he spoke to it but then immediately was forced back to sleep.
My grandparents would tell the landlords about it, and they would never believe it. However, one night they did hear something and the oldman retrieved his shotgun and told his wife to open the door and get out of the way because the noise was right outside the door. She did so and there was nothing there. My dad also had an uncle who boarded with them for a time that had some bad experiences. He got some holy water from a local church and sprinkled it in the house, at which time the disturbances stopped, however they eventually returned. My dad also had an incident when everyone else was on vacation and he was alone for the week. One night he was walking home and he knew that all the lights had been left off. When he got close to the house all the lights were on, then he could not look at the house because he knew that he was being watched.
At my grandmother's funeral in 95, my dad's other uncle, who was very intelligent, softspoken and not given to making things up was talking to my dad in one of the rooms in the funeral home. I myself heard them start talking about the house when the uncle said to my dad "You know, that place was haunted". My dad almost started crying and said "We thought we were the only ones who believed it". He had a VAST look of relief in his face and you could hear it in his voice. I was shocked to hear this.
Keep in mind that with the exception of that particular incident, they told me these things 40 years later after the house was long gone, but I heard it from multiple people on multiple occasions. Also, my dad still has terrifying nightmares about the house.
