My Name is Brendan Grady. My father is John Grady. His Aunt is Anne Parsons. I saw the picture you posted on Google images and sent it out to all my immediate family. No one recognized you. So I dug deeper. I read your short description of your connection with the house and am now writing you. This is all very interesting. I have never heard of your name or the names you listed. I must ask my mother. My father has passed on now 7 years.
Just to note... That house is freezing!! :)
