The true origins of the story of how Dover was named are obscure, but one of the earliest versions was published in "The History of Morris County," 1882, p. 291, by Rev. B. C. Megie, D. D.: "Moses Hurd, the ancestor of the Hurds of this township and vicinity, soon after came from Dover, New Hampshire, and worked in ... [John Jackson's] forge [founded in 1722]. Dover, N. J., was originally called Old Tye; when and how it obtained the name of Dover is uncertain, but in all probability Moses Hurd may have named it after his former place of residence in New Hampshire."
This version of the story, as far as it goes, is typically accepted, repeated and sometimes embellished uncritically in subsequent historical accounts, including in Charles Platt's seminal work, "Dover History," 1914, p. 484. Platt recounts on pages 367-368 his communication with James Lincoln Hurd, a rigorous genealogist of his family's paternal history from Josiah through Moses, Jacob and John Ward, who granted land for Hurd Park to Dover in 1911. The earliest Hurd settler of record was Josiah Hurd, who was born in 1736, 14 years after John Jackson established his forge. So, the Dover-naming story is already in trouble.
It was Josiah Hurd who first migrated to Dover but from Killingsworth, Connecticut, not Dover, N.H., in about 1756 and his son, Moses, was born in Hurdtown, New Jersey in 1771, 18 years after John Jackson had sold his forge in 1753 to Josiah Beaman (Platt, p. 459). So Moses could not have worked for John Jackson because he was born 18 years after Jackson sold out. However, Moses could have worked for Beaman as a young man of 21 before Beaman sold out to Canfield and Losey in 1792 (Platt, p. 459).
To have been the Moses Hurd in the Dover-naming story, however, he would have had to have been from Dover, New Hampshire and not from his birthplace of record, which was Hurdtown, New Jersey. Admittedly, for the Dover-naming story to be true, Moses Hurd could have moved to Dover, New Hampshire after his birth in Hurdtown and then returned to New Jersey to settle in and name what would become Dover, but there are no records yet found to support this theory.
This Dover-naming story is not the first or only one. An earlier story in the 'Iron Era' of 5/29/1875, p. 3, says Jacob Hurd, son of Moses and Dover's first tavern owner, named the town after Dover, New Hampshire where he was from, yet it, too, cites no evidence that he was from anywhere but Dover, New Jersey. This does not help our Dover-naming story, which requires Moses to have named it.
There is yet another Dover-naming story related by James Lincoln Hurd, which, like the one cited in the 'Era,' is an historical outlier (Platt, pp. 367-368). This naming story does not include Moses, but cites a popular Whittier poem as somehow having been the inspiration for the name of the town. So we see that Moses Hurd does not fit into the popular naming story and the story does not fit what is known of Moses Hurd. Who really named Dover still remains uncertain.
