Whitehall NY - First Presbyterian Church Records for Marriage 1855

[suzee01]

Hello - I am looking for the marriage record of my 3rd great granduncle Robert Rennie to Margaret Wildrick in 1855 in Whitehall, NY. In Robert's Civil War military file there is a letter dated 1931 to Senator Thomas indicating that there is an affidavit from Robert and Martha Doig, (who Margaret had been living with and she is on the 1850 US Census with the Doig family), to the marriage of Robert and Margaret at the home of Robert Coleman by the Reverend Louis Gano who was Pastor of the First Presbyterian Church. 
Robert and Margaret were both living in the Whitehall area prior to their marriage and she was born in Ireland and he in Canada.
I have looked at records on Ancestry, Familysearch and Findmypast without success.
Have any records from this church survived and if so can they be accessed online.
thank you for your assistance.
Cheers
Suze

Write back to the National Archives and tell them they did not include all the documents from the file.
Name the affidavit in question.

I had to do this with a Revolutionary War file, I knew from another researcher a letter from a  neighbor existed concerning a marriage that was not included when I received my copies. 


PS I received it at no extra charge.

Thank you for that info - his civil war file indicated that there was no marriage record so I was hoping that after all these years the Presbyterian records for that particular church or Pastor had since been found - the records indicated that the pastor had left the area for parts unknown when they were seeking the marriage record.
