My great grandmother immigrated to America from Vienna in 1907. She was Anna Trval. Her mother was Rosa Walner. Ludwig was her uncle and she lived with him in 1920 (shows on the census) in Erie PA. Also, Ludwig was given money by Steven Trval when he came to America (says on the immigration documentation from Ellis Island- and was his brother in law). I've been looking for info too. I have heard from past stories that the family had a jewelry store on the Walner side. Not sure if this is true or what. Still looking for evidence of this.
