## History
### Medieval

In medieval times the McGovern barony of Tullyhaw was divided into economic taxation areas called ballibetoes, from the Irish Baile Biataigh (Anglicized as 'Ballybetagh'), meaning 'A Provisioner's Town or Settlement'. The original purpose was to enable the farmer, who controlled the baile, to provide hospitality for those who needed it, such as poor people and travellers. The ballybetagh was further divided into townlands farmed by individual families who paid a tribute or tax to the head of the ballybetagh, who in turn paid a similar tribute to the clan chief. The steward of the ballybetagh would have been the secular equivalent of the erenagh in charge of church lands. There were seven ballibetoes in the parish of Templeport. Derrycassan was located in the ballybetagh of Ballymagauran. The historical spellings of the ballybetagh are Ballymackgawran & Ballimacgawran (Irish = Baile Mhic Shamhráin = McGovern's Town).
The earliest surviving mention of the townland name is Doire Casáin, which appears in an interesting list of the rents due to the McGovern Chief, Maghnus 'Ruadh' Mág Samhradháin about 1400 A.D. It reads as follows:
   This is the portion of Doire Casáin- 18 kegs of butter and 8 cakes and half a beef at Christmas and a sheep in autumn and a sheep in summer and two kegs of butter in winter and 8 kegs of meal and as much again in autumn and a keg of butter for Mayday and a gallon of butter for his ploughman in summer.
From this list we see that in 1400 the main type of farming carried on in Derrycassan was milk and beef cattle together with sheep.
A Roman poem from 91 A.D., the Thebaid by Publius Papinius Statius was translated into Irish as Togail na Tebe. This Irish version was transcribed in 1487 in Derrycassan by Diarmaid Bacach mac Parthalain (Dermot "The Lame" MacPartland), in the house of his father, Fineen mac Parthalain. The introduction to the translation translates as
   This book was written A.D. 1487, and in the same year died O'Reilly, to wit, Turlough, son of John; and in the same year were slain the sons of O'Rourke, to wit, Tiernan and Brian Roe, to wit, Tiernan was slain by the sons of MacDermot and by Muintir-Eolais in treachery, and Brian by a son of O'Rourke, to wit, by Owen, son of Felim, son of Donough, son of Tiernan; and in the same year was slain Tiernan Duv, son of Donough Blind-eye Tiernan by O'Donnell, to wit, by Hugh Roe O'Donnell; and in the same year was demolished the castle of O'Rourke, to wit, Felim, son of Donough by O'Donnell and by the sons of O'Rourke; and in the same year the fortress of Lough Oughter was taken possession of by the race of Donnell Ban O'Reilly. It was myself Dermot 'The Lame' MacPartland that transcribed this book, to wit, son of Fineen, son of Foirithe, son of Ferral, son of Farlane; and half of this book was written in the house of Fineen, to wit, in Derry Casan, and the other part of it was written in the house of the descendants of Brian of Tullyhaw, that is the mansion house (the McGovern castle in the townland of Ballymagauran), that is, of Felim, son of Tomas Og, son of Tomas Mor (Feidhlimidh mac Tomás Óg Mág Samhradháin was the chief of the McGoverns at the time the book was written); and it was finished in Inishowen upon Thursday during the feast of St Catherine. (Diarmaid Bacach mac Parthalain doscribh in leabar-sa .i. mac Fingin mic Foirithe mic Fergail mic Partalain & a tigh Fingin doscribad leth in lebair-sa .i. a Doire Casain & a tigh mic Briain Tellaigh-Echach dos-cribad in cuid ele de .i. a tigh arosa .i.

And the hospitality of Felim the son of Thomas the son of Fergus son of that Thomas lord of Tullyhaw during the time when this book was written. And at the same period there were two bishops in the bishopric of Kilmore, to wit, Cormac, son of the bishop Magauran, (Cormac Mág Shamhradháin) and Thomas son of Andrew MacBrady, (Tomás Mac Brádaigh) each one of them alleging that he himself is bishop there; and Felim, son of Donough, son of Tiernan is O'Rourke during the period of those bishops, and John son of Turlough son of John is O'Reilly at that time. And in the same year was slain Ua Mael-Shechlain, to wit, Laighnech Ua Mael-Shechlain, by Conn son of Art ua MaelShechlain. And may the blessing of God rest on the soul of him that wrote this book. And there was war between Magauran and O'Reilly, to wit, John O'Reilly, in that same year; and another war between the descendants of Teige O'Rourke, etc.
Diarmaid Bacach mac Parthalain also wrote or transcribed the following, some in Tullyhaw, probably in Derrycassan. (1) Tochmarc Becfhola or The Wooing of Becfola. (2) Irish translations of romantic tales, lives of saints and other religious texts. (3) Dán do Chormac Mág Shamhradháin Easpag Ardachaidh.
His brother Conall Ballach Mac Parthaláin (Conall "The Freckled" MacPartland) was also a scribe. He produced part of the manuscript Rawlinson B 513 Bodleian Library, Oxford, England.
