Piper's father, George William Perabo, is of German, English, and Irish ancestry. Piper's mother, Mary Charlotte (Ulland), is of Norwegian descent. While Piper's surname is sometimes believed to be Portuguese, it originates in Germany. Piper's paternal great-grandfather, Frederick Joseph Perabo, was born in Lorch, Germany, in 1878, and moved to the United States, where he married Piper's great-grandmother, Edna B., who was also of German descent. Piper's patrilineal line can be traced back to her great-great-great-grandparents, Jacob Perabo and Caroline Diel, who were German-born.
