Hi,
I am a great granddaughter of Amelia Prestopitz and I am stuck on Mary as well. I've always had her maiden name as Ashton, followed by Greenward then Meyers. I have her sister as Nettie so Irma is a new one. I have Nettie married to Eugene Bria and she died in San Francisco in 1943. Nettie's death certificate stated that her mother's maiden name was Davis. So now we have another surname to look at. It's all clear as mud, maybe between us we can figure it out.
