I was recently in Fredonia, Chautauqua County, NY researching the Cranston and Avery surnames. Seth was not one I was researching, but found an old marker, fairly large, with Seth Avery as the deceased. I did not wirte the info down, but you can contact the Genealogy research clerk at: Forest Hill Cemetery Association 57 Lambert Avenue Fredonia, NY 14063. I was unable to locate my husbands ancestor, so I asked the clerk to look it up. They have EXCELLENT records. I am researching Sarah Avery, born 3 Jun 1826 Chester, PA. Died of Neuralgia 16 Aug 1885 in Fredonia, Chautauqua, NY. She married Samuel Cranston in 0.
