We havea Cornelius G. Doremus married Geertie Demarest in 1804. They had 4 children. Ann m. Henry Van Houten, George m. Sarah Huyler, Benjamin D. m. Elizabeth Speer and Eva m. John C. Yorks. I know that this ties into the Demarest line. Am now trying to find out where Jacobusline ties in with it and the Onderdonk line.
