Of territorial origin ham the lands of the same name in the parish of Markinch, Fife. The first of the name on record appears to be Rotheri de Admulti (as the name was at that time spelled: compare Auchincraw-Adincraw), who was one of an inquisition held at Berwick in 1296 which found that Elena la Suchis died seized in demesne in the county of Fife of the third fart of the lands of Disarde and Strathon (Bain, II, p. 216). David de Admulti de eodem was present at the perambulation of the lands of Gaytmilk in 1466 (RD., p. 355), and John Admowtie, who was member of the town council of Stirling in 1565, appears again in 1576 as John Auchmowty (SBR., p. 280). Florentin Auchmouttie had a lease of a tenth of the lands of Halhill and three parts of Melgum c. 1570 (RD., p. 492), William Auchtmowlty was "prebendar of Strigmertyne" (Strathmartin) in 1584 (Soltre, p. 242), Robert Auchmutie, a barber in Edinburgh, having killed another citizen in a duel in 1600 was executed "for having presumed to take the revenge of a gentleman" (Chambers, Dom. Ann. Scot., I, p. 314). George Auchmowtie of that Ilk is in record in 1602 (Fordell, p. 157), and Alexander and John Auchmutie were among the Scots undertakers granted allotments in Ulster in 1610. A descendant of the family of Auchmuty settled at Brianstown, co. Longford, Ireland, in the first half of the seventeenth century, and this Irish branch is now representative of Auchmuty of that Ilk. James Auchinmowtie was captain of H. M. shit The Thrissellin 1628 (RPC., 2. ser. II, p. 179 Achmoutie 1574, Achmowtie 1630, Admowty 1508, Admuty 1450, Aithmutte 1603, Auchinmoutie 1648, Auchmoty 1585, Auchmoute 1603, Auchmouthie 1597, Auchmouttie 1583 Auchmowthy 1551, Auchmowthe 1599, Auchmowthye 1555, Auchmuthe 1588, Auchmowtie 1589. Auchmwtie 1580, Auchmutty 1684.

Four modern variants of this name are reported by local registrars, viz. Achmuty, Ahmuty, Auchmuty and Amooty. The last was in Co. Longford, in which county the family has been established since the middle of the seventeenth century: Arthur Aughmooty appears among the tituladoes for the barony of Longford, Co. Longford, in the “census” of 1659-60; the same man and also another of the name were Poll Tax Commissioners for Co. Longford in 1660 and again in 1661. The name similarly appears at Rathvilly, Co. Carlow. In the seventeenth century the variant spellings included also Aghmooty, Athmooty, Attamooty, Oughmooty and several more, all of which occur in the Irish army lists to be found in the Ormond Manuscripts for various dates between 1662 and 1680. One family came from Scotland at the time of the Plantation of Ulster and first settled in Co. Cavan: in 1611 John Aghmooty and Alexander Aughmooty each obtained one thousand acres in Tyllyhunco, Co, Cavan.

This family coming from Scotland at the time of the Plantation of Ulster first settled in Co. Cavan and later in Co. Longford. SIF 12
