Th century immigrant experience that relates to the book Bread Givers

I chose the topic of the The Golden Land: America as a fantasy. I would like to include a fabrication of my family history in the paper to seem more like my own, my grandparents came over from Naples, Italy on their own and started a family here. My Dad is of one of 7 kids (5girls 2 boys) My grandpa is DDS and my grandma was a stay at home Mom. I want to talk about what the American Dreammeant back then compared to what it means today. Must include an outline of first draft. Also, will this paper be original because I am very worried and have never used this site and we have to turn our papers into turnitin.com to check for plagiarism. Are all papers 100% written from scratch?
