HI, I just came across your inquiry. I lived in Hood river many years. Sorry I have no information on your grandfather, but I remember Maude Peters very well. My husband did some handy man things for her around the yard.
While he was busy Maude would entertain me with tea, and stories. She told us how her husband, (your grandfather?) built the settee not sure what it was called to match other items it had the same old rose covering as the huge drapes in her bedroom. She showed us the whole house. THe one with the big white columns. However there was one room up stairs, she mysteriously would never show us she said it was private, and someone was in there. (My could it have been a memorial room?) Of course she did seem a little eccentric at times. Like asking me to drive her to the store, but she wore her robe and not street clothes. My daughter still remembers her too. Gloria
