I have a David Isacc Doremus born & died the same dates as you. I show he was born in Tappan, NJ. He was married to Eliza M Powers in NY on Sept. 26, 1890. She was born 1814 in NY, died sept 28, 1890. Their children were Ellen E., Rushanna, Sarah J., Eugene A., Oscar F., David F., Charles Henry, Emmal, Emma P., Martha W.Doremus.
John Doremus was David's father born 12/9/1811. Married to Elanor Morris. They were married in Preakriss, NJ. Their children were David I., Eliza Jane, Jacob Doremus.
I have a Johannes Van Houten married to Janneke Doremus born 12/9/1726. Johannes parents were Cornelis Doremus born Holland bet. 1681-1682, died after 1731. Wife Rachel Pieters born Bergen 9/14/1682.
I found on internet Cornelis' father was Cornelis also. he was born abt. 1650 in (France)/(?Middleburg Netherlands). Died bef. 1714. He was married to Jannetje Joris.
My line follows Cornelis' line. I hope this has been helpful. Good luck!!! Jean
