Where are the Rasp family?

Question

My paternal grandpa was Peter Marinus Rasp Jr, born 1906 in the Netherlands. Peter's paternal grandpa may have been Edward who may have been born in Germany or Holland. Some of Edward's children went to NYC. Edward's father may have been Henery who was born around the mid 1850's. I cannot trace the Rasp family line past that.

 

Plus, Peter Marinus Rasp Jr. married a Mary Margaret Hockings who later married Walt Atkins. Peter and Mary were the parents of my father, Donald Melvin Rasp Arnold. My father was adopted into Arnold family. Peter and Mary were also parents to a Peter who only lived for a year and for Ronald Marinus Rasp.

Mary and Walt Atkins were the parents of Jim Atkins. Jim is the father of Josh.

Answer 1

Your family tree profiles that I can see do not show any sources.  I would suggest using familysearch.org for more research and documentation.  You can use the search fields to try different date ranges and locations for censuses, birth, death and marriage  records for your missing information.  Good luck in your research.  :-)
