I believe this Amos Porter b. abt 1730 Lebanon, CT m. abt 1755 Joanna Allen. Their daughter Rachel Porter b. 1766 Lenox, MA m. 1787 Sheffield, MA to Amos Kellogg, Jr. Rachel and Amos Kellogg are buried in Clinton, NY. Also buried there are Capt. Amos Porter who d. 28 May 1814 age 87, making his birth year abt 1737 and Amy Porter, his wife who d. 1 Dec 1813, age 90, making her birth year abt 1723.
There are many Amos Porters and several who were in the Revolutionary War. Is this Amos the son of John and Sarah (Heaton) Porter? Who is Amy? I find no record for the death of Joanna Allen Porter or marriage of Amy ? to Amos Porter. I can only trace my ancestry with certainty to Rachel Porter Kellogg.
