Linda - You are correct. The entry for Maria (Giffin) Purdy on the GenWeb page - and repeated on findagrave.com -is obviously wrong, since, as you have noted, she was alive at the time of the 1880 census. My mother, a great-granddaughter of Gilbert and Maria, noted a death date for Maria of October 20, 1884 -- but no source citation to back it up. Maria's birth date, according to the published genealogy of Simon Giffin & His Descendants, was May 11, 1808. The GenWeb list you reference says there is a "Marion" Purdy buried in the same plot as Gilbert and Maria, with a death date of 1884. That may be Maria, as I know of no Marion in that family. I hope someone is able to get to the Smyrna cemetery and straighten this out for us.
