Randy, I know that my great-grandfather Fred Seaver was born in 1870-so I'm thinking Nathan was born about 1850, but I don't have an actual date yet. I did find out that Fred had a sister named Helen and that she owned a millnery shop in Norwood in (St. Lawrence, NY.) I also know now that Nathans' wifes' name was Katherine Bennett and her mother was Mary A. Bennett, but have no clue yet, as to Nathans'father. Appreciate your trying to help. Thanks, Melissa
