I am responding to your search for decendents of Andrew Derrom. My mother was Helen Derrom (Davison). Her father was Andrew T. Derrom, grandson of the Andrew Derrom that you are asking about. Both my grandfather and mother were born in Patterson, New Jersey. My mother just recently passed away. She was in her 90's. I have additional family history if you are interested. Glad to hear from the family in "Oz".
