ACAYUCA, the capital of a civil division of New Spain, in the province of Goazacoalco, embracing, in its population, 296 families of Indians, 30 of Spaniards, and 70 of mixed bloods. It lies a little over 100 leagues S.E. of Mexico, in lat. 17 deg. 53' N. ACAZINGO, ST. JUAN DE, a settlement of the district of Tepcaca, consisting of 700 families of Indians, 150 of Spaniards, 104 of Mustees, and 31 of Mulatoes. It is situated in a plain of mild temperature, well watered, and has a convent and fountain, and a number of "very ancient buildings." ACCOCESAWS, a tribe of Indians of erratic habits, of Texas, whose principal location was formerly on the west side of the Colorado, about 200 miles S.W. of Nacogdoches. At a remoter period they lived near the gulf of Mexico: they made great use of fish, and oysters. Authors represent the country occupied, or traversed by them, as exceedingly fertile and beautiful, and abounding in deer of the finest and largest kind. Their language is said to be peculiar to themselves; they are expert in communicating ideas by the system of signs. About A.D. 1750 the Spanish had a mission among them, but removed it to Nacogdoches. ACCOMAC, a county of Virginia, lying on the eastern shores of Chesapeak bay. This part of the sea coast was inhabited by the Nanticokes, who have left their names in its geography. We have but a partial vocabulary of this tribe, which is now extinct. It has strong analogies, however, to other Algonquin dialects. Aco, in these dialects, is a generic term, to denote a goal, limit, or fixed boundary. Ahkee, in the Nanticoke, is the term for earth, or land. Auk, is a term, in compound words of these dialects, denoting wood. The meaning of accomac, appears to be _as far as the woods reach_, or, the boundary between meadow and woodlands. ACCOMACS, one of the sub tribes inhabiting the boundaries of Virginia on its discovery and first settlement. Mr. Jefferson states their numbers in 1607 at 80. In 1669, when the legislature of Virginia directed a census of the Indian population, within her jurisdiction, there appears no notice of this tribe. They inhabited the area of Northampton county. They were Nanticokes--a people whose remains united themselves or at least took shelter with the Lenapees, or Delawares. ACCOHANOCS, a division or tribe of the Powhetanic Indians, numbering 40, in 1607. They lived on the Accohanoc river, in eastern Virginia. ACCOMENTAS, a band, or division of the Pawtucket Indians inhabiting the northerly part of Massachusetts in 1674. (Gookin.)
