Nathan Learn, born 1830 in NY, died 1897 was the great great grandson of John Learn who married Cadarina LNU. To date I don't know if Cadarina's maiden name has been discovered. Nathan was married to Arvilla Cooper, 1830-1898. Both are buried in Dutch Hill Cemetery in Ischua, Cattaraugus Co., NY. Nathan is my great great grandfather. I'm looking for Arvilla's parents. Can anyone help?
