D’Linton Greenfield, a Rome, Oneida, New York book seller and stationer, was the son of Joseph and Cynthia M. Hubbard Greenfield. According to his obituary (found in a scrapbook at the Rome Historical Society and likely clipped from the Rome Sentinel), he was born in Trenton, Oneida, New York on 25 Jun 1846. D’Linton married Georgianna Schryver in Rhinebeck, Dutchess, New York on 2 April 1885 (again, from a newspaper clipping found in a scrapbook at the Rome Historical Society) and they had one daughter. D’Linton died in 1919 and is buried in Rome Cemetery.
D’Linton is a fascinating name and it doesn’t appear to Google. If you’ve heard it before or know where it might have originated, please let me know.
