Segheswyk in the rolls of collectors of subsidy to King Richard II in the West Riding of Yorkshire l378-1379. In 1563 Seeggeswyke; between 1611 and 1619 the Parish registers of Dent, Sidgsweeke; in 1624, Siddswicke; between 1645 and 1698, Sidgwick or Sidgswick; between 1700 and 1737 the name is entered thirty-six times; of these, two in 1701 and l736 give Sidgwick; all the Sidgswick.

"The earliest Sedgwick at Dent appears on tomb of Rev. James Sedgwick, great uncle to Adam Sedgwick who died in 1780, but in his registry of baptism, 30 Sept. 1715, he is entered as son of John Sidgswick. Adam Sedgwick maintained that the spelling of the family name was deliberately changed by this James Sedgwick, at the suggestion of the then master of Sedberg School.

"On the other hand, a branch of the family who had settled at Wisbeck, Isle of Ely, called themselves Sedgewick (or Sedgwicke) at the beginning of the 17th century (Visitation of Cambridgeshire, made in 1619, by Henry St. George, Richmond herald; printed by Sir Tho. Phillips, Middle Hill Press, 1840,) and they are said to have adopted a characteristic crest, a bundle of sedge bound up in a form like that of a wheat-sheaf."

Along this same -line of thought we quote from a letter frcm a Mr. George Sedgwick, of Leicester, England, written to Mr. George H. Sedgwick, of New Jersey, later of Rochester, N. Y., who described himself as "a retired Civil Servant of His Majesty, and a Justice of the Peace for the Borough of Leicester," as follows; "For many years past I have been interested in our family tree, and have tried to trace the source of our surname, and with a certain amount of success. Traveling through nearly all the large towns of the United Kingdom, I have found persons of our name, tho always few in number, in many parts of the country, but mainly in the Northern parts of England.
