Uncas.—The author is indebted to the Committee of the Historical Society of Massachusetts for an opportunity to examine a valuable document recently forwarded to them by Mr. Williams, of Lebanon, Connecticut, and originally, we believe, a part of the Trumbull collection.

According to this account, which purports to have been "made by Uncas" himself, that Chieftain was wholly of the royal blood of the Pequots. Tatobam was another name for Sassacus, and Uncas married the daughter of that Sachem (from whom he afterwards revolted,) about ten years before the Pequot War. The Pequots and "Moheags," as they are here called, jointly agreed to this match in a grand Indian Council, for the purpose of keeping their land entire. "Upon this his right to the Pequot Country was good and unquestionable." . . . "Quinebauge [New-Haven] Indians and Nipmugs [in Worcester County, Massachusetts] not allowed to marry in the Royal Blood—agreed to keep the Royal blood within the Realm of ye Mohegan and Pequots."

In this genealogy, which is regularly derived, as accurately as possible, from remote ancestors on both sides, Uncas himself is styled the Sachem of Mohegan, and Mohegan is said to have been the Sepulchre or Burial-Place of both the Pequot and Mohegan Sachems.

The father of Tatobam was the Sachem Wopegwosit. The father of Uncas was Oweneco; his father, Wopequand, a Pequot Sachem. His mother and grandmother were both named Mukkunump; and the latter was daughter of Weroum, a great Narragansett Sachem, and of a Squaw of the royal Pequot Blood named Kiskhechoowatmakunck. One of his great-grandfathers, Nuckquuntdowaus, was Chief-Sachem of the Pequots; and one of his great-grandmothers, Au-comp-pa-hang-sug-ga-muck, (as nearly as we are able to decipher it,) was "a Great Queen, and lived at Moheage."

The son of Uncas, (mentioned in the text,) was Oweneco. Several of his other descendants who inherited the Sachemdom were named Ben Uncas,—one of them Major Ben. The last of the Sachems (also mentioned in the text,) was Isaiah,—a grandson of Oweneco or Oneco. (He was a pupil in Dr. Wheelock's Charity School,—"a fat fellow, of dull intellectual parts."—Mass. His. Coll.)

The document before us gives an account of the cession of the Pequot Country from Uncas by deed, dated Sept. 28, 1740. The following remarkable passage ought not to be omitted, as it adds new confirmation to the estimate of the Sachem's character which the author has given in the text.

"Afterwards sufficient planting ground was provided for him, being friendly to the English, though only to serve his own purposes."
