Early Acheson Settlers

of Tyrone County

Refer to the Cookstown Poorlaw Union Map or to the Derryloran Parish Townlands Map as necessary.

There are several possible early ancestors for the Achesons of Cookstown, Co. Tyrone, and though they may perhaps be closely related, of this we are as yet uncertain. The earliest mention of an Acheson in County Tyrone yet uncovered, is in the vicinity of Cookstown. Occuring understandably during the period in which Scottish "planters" were taking and developing land in Ulster, we find several mentions of a Robert Atcheson (also Atchison, Atginson, Atkinson) in the early Summonisters Rolls, Tyrone Assigns of King Charles I.

Robert is cited several times between the years of 1625 to 1629 as a Gentleman of Kilmoon, and Seneschal of Donaghmore Manor [Bottom of Map]. He is also cited in two undated earlier Summonister Rolls from roughly 1615 to 1622. Judging by the dates of his apparent Plantation, and his "Gentleman" status it appears that he was granted some parcel(s) of land in Kilmoon (probably Killymoon today) [Map (1)] probably around the commencement of the Plantations in 1609 under King James I. Also cited among the early Tyrone Assigns, was a Henry Achinson (1622) who probably is the same who was also granted lands over the county border in Armagh (2000 acres), and whose brother Archibald became the ancestor of the Earl's of Gosford at Markethill after Sir Henry passed him his landholdings.

This Gentleman Robert Atcheson may well have been related to the Acheson brothers Henry and Archibald who coincidentally or not took lands very near to Robert, and were later knighted in the mid 1620's (probably indicating that like Robert, they were also Gentlemen prior to Knighting). This being the case, Robert too may have originally been from the region of Edinburgh where the brother's came from, since there was a heavy population of Achesons in Edinburgh during the 1600's, many of whom seem to have been of substantial means. The early Achesons of Edinburgh appear to originally have dwelled just east north-east of Edinburgh (15 to 20 miles) at what was then called Gosford House. A sheltered bay on the south shore of the Firth of Forth (near the Gosford estate) took its name from this family in the mid-1600's, being called "Aitchison's Heivine".

Robert's rank as Seneschal indicates that he was Steward of, and saw to the household affairs of Donaghmore Manor. The manor was probably owned by someone of better means, who may not have taken a great interest in these Tyrone lands at this early time, or perhaps the Donaghmore property was even owned by a relative of Robert's.

Robert Atcheson, Gt. would have been a contemporary of James Stewart who took possesion of a small parcel of land in Ballymenagh [Map (4)] in 1620. As contemporary gentlemen and neighbors in this sparsely populated region they would almost certainly have known of one another, if not having known each other personally. James Stewart of course later became the grandfather of William Stewart who features so prominently in Cookstown's history as the primary early developer of "Cooke's town" [Map (3)] during the 1730's and 1740's.

Other possible progentors of the Cookstown line of Achesons might be derived from Achesons who settled in County Armagh, which includes- Sir Henry and Sir Archibald of County Armagh from 1612+; William Acheson who settled on the Hamilton Estate (1629-30) in Killycarn, Loughgilly Parish, County Armagh; Nathaniel Acheson recorded in the Muster Roll of 1630 in Oritor? Barony, Armagh Co. as Lord Mountmorris' man-at-arms; or Robert Acheson who settled on the Gosford Estate (1630), in Fews Barony, Markethill, Co. Armagh

By 1659 we find that a Patrick Acheson is of Omagh, Drumra Parish, Co. Tyrone, and appears to have commenced a line of Acheson descent in the vicinity of that town.

During the period of William Stewart's restructuring of Cookstown (plans being drawn up in 1734, and completed in the 1740's) we find that a David Atchison was a farmer of Loy (Hill) [Map (2)], Derryloran Parish, Co. Tyrone (1735-6). Thus David was a contemporary of William Stewart's and an early citizen of the redesigned community of Cookstown. Assuming that David was born ca. 1700, he might be presumed to be the Grandson or perhaps Great-Grandson of Robert Atcheson Gt. of Kilmoon. Note that the modern day "Killymoon desmesne" lies southeast of the small townland of Loy.
