Crum Secor lines in Rockland County, NY

I have made application to DAR through the Patriot, Joseph Washburn. This line is mostly in Rockland County, NY. My application has been rejected as I need more information. The types I need are Church records and I do not know what Church they attended. Those in question:

Mary Evaline Crum married William Secor
Birth JAN 1864 • New York (probably the Ramapo area)
Death 23 DEC 1900 • New York, New York

Emma C Washburn married Edward Crum
Birth ABT 1844 • New York
Death BEF 1875

Whitson Washburn
Birth 01 NOV 1809 • Westchester, New York
Death 05 MAY 1868 • Montebello, Rockland, New York

If anyone has information or suggestions on where I might look, please do not hesitate to contact me at: Robinflannery@optonline.net or please answer in this Forum.

Thank you.
