I also come from the same Porter family. I have the text of an obit from the Dansville Express dated 27 Feb 1879 regarding Capt David C Porter and would be willing to share that with you if you are interested.
William Porter married Anne Oukee 3 Oct 1768 in Hunterdon County, New Jersey. She was born in 1744 and died 12 Nov 1798. She is buried in Greenmount Cemetary, N. Danville, Livingston County, NY.
