The Armorial Tomb of the Rev. Joseph Eckley

Once again, The Heraldic Journal, Vol. II, pp. 128-129, gives us a lot of biographical and genealogical information about the owner of this tomb:

“The Rev. Joseph Eckley, D.D., was born in London 22 Oct., 1750, His father removing to New Jersey, about 1767, he was graduated at Princeton in 1772. He was ordained as the successor of Mr. Hunt at the Old South Church in Boston in 1779, and remained there till his death, 30 April, 1811.” Dr. Allen’s account, from which we collect these facts, furnishes other particulars of his ministerial labors.
        Mr. Eckley married Sarah Jeffries, and had three sons, Joseph, Thomas, and David.
        Joseph died unm. at Marblehead, about 1860.
        Thomas m. his cousin of the half blood, Julia Ann Jeffries, and had Julia Ann, now deceased; Sarah, wife of Prof. H. L. Eustis of Harvard College; and Elizabeth, wife of Thomas Rhett. David Eckley m. Caroline S., daughter of Jonathan Amory of Boston, and had Joseph S. of Buffalo, David, Edward (deceased), John L., William (deceased), Henry of Framingham, Arthur A. and Frances A. Mrs. Eckley died in June, 1866.

And Preachers, Patriots & Plain Folks: Boston’s Burying Ground Guide to King’s Chapel, Granary and Central Cemeteries, by Charles C. and Suzanne Austin Wells, adds: Rev. Joseph Eckley (1750-1811) ae 61, Loc Tomb 67, called “the evangelist,” he served 2nd Baptist Church 1790-1826 and edited the Baptist Missionary magazine for 23 years. Honorary degrees from Brown University and Union College.

Bolton’s An American Armory cites: Eckley. Gules three swords in fess paleways points upward argent hilts and pommels or the middle one surmounted by an inescutcheon bearing a dexter hand couped. (Given the usual heraldic defaults, this blazon could be made a little shorter: Gules three swords in fess proper, the central one surmounted by an inescutcheon bearing a dexter hand.)
        Crest: A dexter arm embowed and armed.
        Rev. Joseph Eckley, D.D. Box tomb, 1811, Granary Burying Ground, Boston. Heral. Jour., vol. 2, p. 128. These are the arms of Clarke of Salford, Co. Warwick, Baronet.

Researching Burke’s General Armory for Clarke of Salford, we find: Clarke (Salford, co. Warwick. See Woodchurch. These arms were confirmed as a quartering by the Deputies of Camden, Clarenceux, to Sir Simon Clarke, 19th in descent from Clarke Woodchurch, who m. Susan, dau. and heir of Henry Clarke). Gules three swords in pale argent. Crest—A fleur-de-lis per pale argent and sable.

Looking further for Woodchurch, we find only one: Woodchurch (Woodchurch, co. Kent). Gules three swords in pale argent.

Burke also cites: Clarke (Shirland, co. Nottingham, bart.). Gules three sword erect in pale argent hilts or. Crest—A hand couped at the wrist proper holding a sword as in the arms.

I am left thinking that there is more to it than what Bolton and Burke are showing us, because the crest on the Eckley tomb does not match either of the Clarke coats of arms cited. On the other hand, the only Eckley to be found in Burke matches neither the arms nor the crest shown here.

So we are left with a bit of a conundrum: where did the arms and crest on the Eckley tomb come from? I am at a loss to say.
