Yes, the name is 'Peder' and no, the 'd' is not a typo. I was named after two great grandfathers (both Norwegian, by the way) whose names were both Pe*er (*=t or *=d), but my mother got to the birth certificate first and for her grandfather *=d. Evidently the name selection process had been entirely verbal since my father's response is reported to have been "What's with the d?" when he saw the certificate.
Yes, every data entry person on the planet thinks it's a mistake and changes it. However, these same data entry folks have also renamed me "Epder" and "Prfrt" (check out a computer keyboard to figure out the latter).
